An idiotic conspiracy theory is making the rounds in Canada’s alt-right media (yes, we have one too).

Here's how it goes: Despite what the lying media told you, last month’s mosque shooting in Quebec city was actually an act of Muslim on Muslim terror carried out by a Moroccan jihadist from a rival mosque. But Justin Trudeau couldn't let the truth out since it would make him look bad for taking in all of those Syrian refugees. So, the powers that be offered the shooter a sweet deal: He'd be released without charges if he backed up their official story, that he was arrested in error while providing first-aid to people shot by the real killer, who according to police is a white nationalist named Alexandre Bissonnette.

It's total bullshit (duh). Even the premise is absurd: Why would a terrorist attack by a Moroccan jihadist make Trudeau look bad for accepting Syrians? Then there’s the crazy notion that the cops would be cool with letting a mass murderer walk because of political pressure from Trudeau. Also, what about the dozens of survivors who could refute a revisionist account? Debunking this nonsense is hardly worth the effort, as any dummy who buys it won't be swayed by things like facts and reason anyhow.

I bring it up now to point out something far more disturbing than the conspiracy theory itself; namely, the fact that there are more people in the alt-right credulously discussing and sharing the conspiracy version of the shooting than there are people in the mainstream conversation recognizing what actually happened in Quebec.

What actually happened is that Canada suffered the world’s first terrorist attack carried out by an extremist who was radicalized by the new online right and whose political guidestars included Donald Trump.

Here’s what we know so far about Bissonnette: He was a right-wing troll, a white-nationalist and an anti-feminist. He didn't just "like" Donald Trump on Facebook. He also championed Trump in arguments, trolled pro-immigration forums, and defended the president's Muslim ban.

In fact, the ban directly anticipated the mosque shooting. In defending the ban, Bissonnette railed about his fears regarding the "marginalization" of the white race. A day after he wrote that, he allegedly walked into a mosque and allegedly opened fire into a crowd during evening prayer, killing six people and injuring many more.

Bissonnette’s Facebook history reportedly contained glorified Christian Crusader imagery, a popular meme of Trump's online supporters.
