Baltimore, United States – Muslim Americans are grieving after two gunmen last week opened fire at the Islamic Center of San Diego, killing three people.

But at the annual conference for the Islamic Circle of North America (ICNA) in Baltimore, community leaders stressed the urgency of turning the sorrow into action.

Nearly 25,000 people turned out for the annual event, held on Saturday and Sunday. Speakers addressed the recent shooting, pointing to the courage of the three victims as examples for the broader community in a time of heightened Islamophobia.

“We owe them more than condolences. We owe them resolve,” said Lena Masri, a lawyer at the Council of American-Islamic Relations (CAIR).

She explained how the victims — a security officer, a caretaker and a neighbour — sacrificed their lives to save others. The security officer, Amin Abdullah, exchanged fire with the shooters, while the other two victims, Mansour Kaziha and Nadir Awad, rushed to help and called for emergency services.

“They protected the physical space of our community: the masjid [mosque], the school, the children, the teachers, the worshippers,” Masri explained.

“Our responsibility is to protect the civic space of our community: the right to worship, the right to speak, the right to organise, the right to defend Palestine, the right to build institutions.”

That was the recurring theme of the conference: that the Muslim American community cannot afford to be passive and must draw on its strength to push back against bigotry and hate.

Speakers emphasised voting, organising and donating to community institutions and candidates who align with Muslim Americans. They also underscored the need to hold officials accountable and push for an end to Israel’s atrocities in Palestine.

“We owe Gaza more than grief. We owe Gaza advocacy that cannot be intimidated into silence,” Masri said.

Islamophobia and Palestinians’ dehumanisation

Symbols of Palestine could be seen everywhere at the conference, from bags emblazoned with watermelons and flags to keffiyeh-patterned scarves, shirts and water bottles.

At a bazaar featuring dozens of vendors, conference-goers left messages of solidarity on a tent that will be sent to Gaza by the charity Life for Relief and Development (LIFE).

In speeches and on panels, advocates drew a link between anti-Muslim bigotry in the United States and Israel’s abuses in Gaza, the occupied West Bank and Lebanon.

Some of the loudest promoters of Islamophobia in the US are also staunch Israel supporters, among them right-wing commentator Laura Loomer and Congressman Randy Fine.

Both Loomer and Fine are allies of US President Donald Trump, whose administration has unleashed a crackdown to deport critics of Israel who live in the US but are not citizens.

Altaf Husain, a professor at the Howard University School of Social Work, said anti-Palestinian voices are trying to “scare” Muslims as a means of silencing criticism of Israel.

“They want to shut this down, so it’s a direct connection,” Husain told Al Jazeera.

He said the large turnout at the ICNA conference shows that the community is not intimidated and will not back down.

In the response to the shooting in San Diego, Husain pointed out that the community raised more than $3.5m for the victims’ families and moved to bolster security around Muslim institutions.

Layers of security

Saad Kazmi, the president of ICNA, said the organisation relied on three layers of protection to secure this weekend’s event: its own security guards, an outside firm and local law enforcement agencies in Baltimore.

While there is anxiety in the community over the rise of Islamophobia and Trump’s immigration crackdown, he said Muslim Americans must take matters into their own hands and work with “sensible” people across the political spectrum to defeat hate.

“We are very thankful that we live in a country that is ruled by the Constitution and law,” Kazmi told Al Jazeera.

Kazmi added that the shooting in San Diego only added to the community’s determination to assert and protect its rights. The Islamic centre in the city, he noted, did not shut down after the attack.

“If anything came out of this, it is that there are more attendees to the masjid, more people who believe that the way forward is to strengthen ourselves, strengthen our community and march on,” Kazmi said.

After the shooting, Loomer doubled down on her anti-Muslim rhetoric, calling on immigration authorities to target the Islamic Center of San Diego.

She also called for the deportation of all Muslims from the US, describing them as an “invasive species”. But few Republicans disavowed Loomer, who maintains close ties to the White House.

Rather, more than 60 Congress members have joined the Sharia-Free America Caucus since it was established in December. CAIR has designated the caucus a hate group.

At the state level, governors and local legislators have disparaged Islam while also pushing to penalise Palestinian rights activism.

Texas and Florida, for example, have labelled CAIR a “terrorist” group, while implementing measures against “Sharia law” that critics consider anti-Muslim dog whistles.

Rights under attack

In March, after CAIR sued Florida Governor Ron DeSantis over its “terrorist” designation, a federal court blocked the label from being imposed.

In his ruling, Judge Mark Walker wrote that DeSantis’s executive order (EO) targets the Muslim community as a whole.

“It should be lost on no one that Defendant’s EO targets one of America’s largest Muslim civil rights organizations for indirect suppression of speech. But, as we all know, it is easy for those in power to target minority groups with little pushback,” Walker wrote.

“Sadly, history teaches that it is often minority religious groups who find themselves in the crosshairs.”

On Saturday, several panels praised the US legal system and the laws that protect freedom of religion and speech. But the panellists argued that human rights do not defend themselves; people must step up to protect them.

“You’ve got to imagine rights are a territory, and you have to occupy that territory. If you do not actively occupy that territory, that territory will be taken from you. And that is exactly what has been happening,” Tom Facchine, an imam from New Jersey, said.

Last year, Palestinian immigrant Leqaa Kordia found her rights in jeopardy when immigration agents knocked on her door and detained her over her activism against Israel’s genocidal war in Gaza.

Kordia spent more than a year in Immigration and Customs Enforcement (ICE) detention before an immigration judge ordered her to be released in March.

But Kordia — who is still fighting deportation — told ICNA conference attendees on Saturday that she has no regrets, encouraging them to remain politically active and engaged.

“Speaking up, it comes with a cost … It cost me my health, my life, literally my freedom, and I’m living in uncertainty that tomorrow I’m going to be here, or I’m going to be deported,” she said.

“It comes with a cost, but it’s worth it. It’s worth it because silence, it costs even way more than speaking.”
