US President Donald Trump caused an international incident this week when he promoted the propaganda of one of Britain’s most infamous anti-Muslim activists.

Early Wednesday morning, he re-tweeted a leading figure of the anti-Muslim Britain First movement, prompting UK Prime Minister Theresa May to rebuke him and the Dutch government to fact-check him.

“The fact that we work together does not mean that we’re afraid to say when we think the United States has got it wrong, and be very clear with them,” May said. “And I'm very clear that retweeting from Britain First was the wrong thing to do.”

Justin Trudeau has remained completely silent. As the leader of Canada, home to at least a million Muslims (and a supposed bastion of liberal multiculturalism), Trudeau needs to join this chorus and issue an immediate, unqualified condemnation of Trump’s actions.

This isn’t the first time Trump has promoted anti-Muslim material. By all accounts, it’s in fact the eighth — eighth — time since the beginning of his presidential campaign that he has explicitly propagated an anti-Muslim falsehood in order to smear that community.

That Canada has yet to come out with a public condemnation of this string of racist behaviour is unacceptable.

Trump’s retweets were of Britain First’s deputy leader, Jayda Fransen, who posted three videos alleging violent behaviour by Muslims and migrants. The Dutch government has debunked one of these videos, noting that the “migrant” Fransen refers to in her tweet is actually a Netherlands-born man who ended up doing time for his behaviour. The other two videos were of incidents in Syria and Egypt, and were tweeted with no reference to any context whatsoever.

“Facts do matter,” tweeted the officials at the Dutch embassy in DC.

Here are some other facts: “Britain first!” was what Thomas Mair yelled when he shot and stabbed left-wing Labour Member of Parliament Jo Cox to death in broad daylight last year, later calling her a “collaborator” against the white race. Fransen was also convicted recently for harassing a Muslim woman wearing a hijab while conducting one of her “Christian patrols” of neighbourhoods known for having a significant Muslim presence. In other words, this group is no longer shy about publicizing its bigotry.

Then again, these facts only matter to those who want them to matter. Plenty of right-wing politicians in the Western hemisphere today are hard at work trying to exploit the current populist atmosphere by dog-whistling to a far-right contingent through anti-immigrant or tough-on-crime/terrorism messaging. But Trump has, by all indications, gone beyond even this superficial attempt at propriety when it comes to Muslims.

Trump has, among other things, campaigned on banning all Muslims from coming into the United States, lied about Muslim Americans not wanting to report the perpetrators of the San Bernardino massacre, and asserted wrongly that thousands of Muslim in New Jersey celebrated 9/11. This is all in keeping with the racist and sexist fodder that seems to pour out of his administration (and his private life) on a regular basis. And it has been happening for years.

Trudeau, who bills himself as the progressive and feminist choice for Canadian leadership, has yet to issue a truly explicit condemnation of these patterns.
