Here's the thing: if one is a southerner in the US, one might plausibly claim that a stars & bars patch or flag might have some other meaning than white supremacy. One could pick up some affinity via osmosis, relatives, peer pressure, bad history teachers, whatever. I tend not to buy that excuse, but I can see how it might mitigate things a bit.
However, if one is attaching oneself to the Confederacy while living in Canada, Europe or any place other than the old South, one is attaching oneself to white supremacy deliberately. And, yes, Confederacy = White Supremacy as the movement was based on the idea that whites can/should own black people (read any of the articles of secession), making it the highest form of White Supremacy (borrowing a smidge of Lenin). So, yes, affinity for Confederacy and its symbols means affinity for White Supremacy, and, yes, all that almost always comes with it--anti-semitism, homophobia, xenophobia, Islamophobia and even misogyny.
The outlet is now trying to distance itself from white supremacy, but it may have a hard time doing so. Why? Because it has long been more than a smidge racist. Stephanie Carvin pointed it out quite clearly today:
The skittles, as folks might remember, were reference to the "poisonous" Muslims among the Syrian refugees. So, yeah, not so cool.Just a reminder that everyone now leaving the Rebel was totally cool when Ezra Levant was tweeting crap like this. pic.twitter.com/Z8AJOWraez— Stephanie Carvin (@StephanieCarvin) August 17, 2017
And the folks jumping of the Rebel ship now should still be considered tainted by their previous association since its racism and other fatal flaws are nothing new.
