Characters I've personally seen get a hate following:
Men: Dale, Angus, Sven, Clinton
Women: Marigold, Dora, Faye, Tai, Claire
4 to 5 when more characters are women than men in the comic seems pretty... well, it just seems pretty unremarkable.
Now, I can't say there is NO -isms in this. The hate of Claire from some people has had obvious -ist behaviors involved, though people who make that obvious tend to get booted pretty fast. And yeah, is there probably the occasional sexist member that compounds the issue of a certain characters hate? More than likely yes.
But it just doesn't seem like its really extreme enough in that direction to pin it all or even mostly on that.
I'm willing to pin it on my bias, too. I just don't know. I haven't noted Angus, Dale, Sven provoking a sustained, multi-source, multi-directional criticism of everything they do every time they appear.
Clinton, yes. But as I said, Clinton's job is to provoke that reaction. Whatever else, we aren't really supposed to like him.
Momo's weapons system use on Clinton was the most obvious example. He's a creep, but there was probably a response below "knock him out of his shoes." It wouldn't have been funny, though. To the extent that Faye's criticized for her violence, it was all in service of a laugh. I happen to agree that if the genders were reverse, it wouldn't be funny, and that makes it a valid issue. Momo being a thing that can't exist in our current world doesn't really change that, IMO. So I have to hang my head and admit that I'm wrong because I still think it's funny.
I'm just saying that, technically speaking, it's the same as Faye's violence (which I also still find funny).
So, while I'm throwing out mea-culpas, it's worth noting that I meant the preamble. It's not about -isms, or people being an -ist. (Granted, the Claire problem tends to be exactly about that, but ban hammers fall like Thor's in the house, so...) It's just the potential for unexamined biases. It's not like I even thought of the problematic side of Momo's violent traits before today. I never examined it. Now that I have, I don't know that I won't laugh, chuckle, or guffaw next time it comes up.
I guess, unrestrained, it could become a problem of -isms, as unexamined biases are wont to. Then again, could just be my bias. Different points of view welcome, and all that.
