I mean, Spork's evidence is all anecdotal. Search enough and you'll find a handful of idiots posting really, really stupid stuff. It doesn't make them a meaningful force, though. I'd love to see some statistical evidence, but I'm not sure that's possible with what we're talking about here. Social media is a cesspool full of trolls.
I just think the outrage machine is overworking itself for this one, based on what I've seen so far.
