The thing is that while yes, Wheaton is clearly a complete and total spineless wimp in real life, capable of doing little more than screeching autistically about you on his twitter once he gets home, those are actually the sorts who are the most likely to be abusers.
Because yes he's a pale, weak, pathetic, emasculated shadow of a man... and he knows it. What's more, he has to play up that image because that's what's expected of him in the subsection of society he occupies... to be a soft, nonthreatening, ball-less wonder who spends all his time groveling at the feet of the glorious goddesses that are women and pronouncing all men to be scum. Most of them don't really believe that shit though, so they simmer in resentment, building up an internal reservoir of hatred that would put any self-professed incel to shame.
So when they get the chance they're totally going to go for it. Now the mistake most people make is thinking that since Willy couldn't physically overpower a woman or force her to keep it quiet that he's therefore got no chance. The thing is that these sorts rely on social manipulation and power disparities. Basically, they use the very methods that they so loudly decry when they're #MeToo-ing to get their way. Which is why, awhile back, we were discussing his involvement with Suicide Girls. That's exactly the sort of environment a camouflaged predator would seek out, because there's lots of no-names, or up-and-comers who wouldn't want to jeopardize their chances by accusing a nerd icon, they're already taking naked photos for money so their credibility is low in the eyes of the general public, it's the perfect setup for someone like Wheaton to vent all that pent-up misogynistic rage and power lust.
