So there's this absolute scumbag in North Carolina who hates gay people, and also happens to be blind.
In the last few days I've seen a ton of people mock him for not looking at cameras, or 'the weird way he moves his eyes.' It's a textbook example of why focusing criticism on someone's physical traits is never a good idea.
Most folks I've pointed this out to are suitably chagrined, and I appreciate them <3. A few try to defend themselves. He's a scumbag, so there's no holes barred on insulting him, right? No.
When we mock a bad person for being blind, or fat, or trans, we're telling everyone with those traits that we secretly think they're less than wholly human. Maybe we won't admit it so long they remain "good," but we've admitted that it's there under the surface.
