I'll spell it out a bit more.

Since, as a member of a minority group, they probably get more negative feedback than average, and since probably most of that negative feedback is due to x-ism, why shouldn't they assume you're an x-ist?

And that's completely leaving aside whether there exists any sort of stereotype that members of group x aren't as smart or capable as non-x folks that you may be playing into.

It's really on your shoulders to indicate or demonstrate that you're just an asshole and not an x-ist asshole. Because, as far as the various x-folk are concerned, isn't it simpler to assume that a non-x is being an asshole to them because of x-ism? Odds are that they're right.
