For too long, terror attacks have been depicted as a uniquely Muslim problem, with acts of violence described as "terrorist only when it applies to Muslims," said Abbas Barzegar of the Council on American Islamic Relations. He works on documenting and combating anti-Muslim bigotry and Islamophobia.
"We've got an issue in this country where anytime a violent act is committed by a Muslim, the media starts at terrorism and then works backward from there," added Colin Clarke, a senior research fellow at the Soufan Centre, a New York-based think-tank.
It's the opposite when the shooter is non-Muslim and white, said Clarke, who's spent his career studying terrorism, particularly Muslim extremism.
The March 15 attacks in Christchurch raised questions about whether Islamophobia and the threat of violent right-wing extremism was being taken seriously by politicians and law enforcement.
US President Donald Trump expressed sympathy for the victims, but played down the rise of white nationalism around the world, saying he didn't consider it a major threat despite data showing it is growing.
The Anti-Defamation League found that right-wing extremism was linked to every extremist killing in the US last year, with at least 50 people killed.
The group said that since the 1970s, nearly three in four extremist-related killings in the US have been linked to domestic right-wing extremists and nearly all the rest to Muslim extremists.
"It's really important that this attack not be dismissed as some crazy lone wolf, isolated incident," said Dalia Mogahed, who leads research at the Institute for Social Policy and Understanding, an organisation that focuses on research of American Muslims.
"I think it needs to be seen as ... a symptom of a wider problem, a transnational rising threat of white supremist violence where anti-Muslim rhetoric is the oxygen for this movement," she said.
A study by the ISPU found that foiled plots involving Muslims perceived to be acting in the name of Islam received 770 per cent more media coverage than those involving perpetrators acting in the name of white supremacy.
Another study by Georgia State University found that out of 136 terror attacks in the US over a span of 10 years, Muslims committed on average 12.5 per cent of the attacks, yet received more than half of the news coverage.
Mehdi Hasan, a commentator, TV host, columnist and adjunct professor at Georgetown University, said the public has been conditioned since the 9/11 attacks to see terrorists "as people with big beards, brown skin, loud voices shouting in Arabic".
He added: "I don't think anyone can deny that the entire 'War on Terror' has fed into this idea (of) Muslims as a threat, as 'the other', as inherently violent."
Clarke said he's been called to testify on Capitol Hill three times in the past two years about jihadi terrorism. "Where are the hearings about right-wing violence?" he asked.
Sectarian, cultural and ideological differences among the world's Muslims complicate efforts to uniformly push back against negative stereotypes — including the perception by some that Islam condones or encourages violence.
Such biases have been exacerbated by multiple attacks by Islamic extremists in European capitals and by years of conflicts that seem to pit Sunni and Shia Muslims against each other.
In the Middle East, the victims of extremist violence have often been fellow Muslims, targeted by groups like Isis or al-Qaeda because they don't share their hardline ideology.
Isis (Islamic State), which promoted an extremist version of Sunni Islam, terrorised millions of people during a five-year reign in parts of Syria and Iraq that only ended at the weekend, with the loss of the last speck of land of its self-proclaimed caliphate.
Some leaders of majority-Muslim countries have been accused of exploiting the debate.
Turkish President Recep Tayyip Erdogan stirred controversy when he was seen as politicising the Christchurch attacks to galvanise Islamist supporters during a campaign ahead of municipal elections. Erdogan screened clips of the attack — despite New Zealand's efforts to prevent the video's spread.
Mogahed, who co-authored a book called Who Speaks for Islam: What a Billion Muslims Really Think based on interviews with tens of thousands of Muslims around the world, said it's important to ask whether someone needs to be speaking for Islam, particularly when other groups of people are afforded the presumption of innocence when horrific acts are carried out in their name.
Some Muslim community leaders, like Dawud Walid, an imam in Detroit, said they are troubled by demands that Muslims condemn extremism carried out in the name of Islam. This suggests that Muslims share some sort of collective responsibility for the actions of extremists.
Hasan says this "subliminally reinforces the idea that terrorism is a Muslim problem."
