you label her as an 'outsider' to gaming culture
Well A) I didn't... and B) It wasn't a reference to gaming culture but rather to that person's viewpoint.
Now even if you didn't mean that in the way she took it (eg, literally)
I doubt she did, I explained it and if Vector honestly felt like I was just attacking her further she would have said so.
Here's the problem though. When Vector outlined some personal experience of sexism she had UltraValican dismiss her experience as invalid
Not a problem, call him out... keep it civil. Disagree, debate.
Didn't Anita Sarkeesian at one point say "Mirror's Edge is too hard for women"? I don't think I'd want anyone who thinks stuff like that to represent feminism.
I highly doubt she said that... I'd want to see it.
Since that would be a dumb thing for anyone to say.
"Women obviously don't know anything more than men do about sexism, despite being subjected to it on a daily basis in more harmful ways than men."
I'd actually would agree with that statement. Perhaps not "as a whole" due to how society works... But a woman doesn't get a sexism level up just because it occurs to her more often. A person who receives a lot of injuries isn't anymore equipped to treat them then someone who never experienced one.
There is a reason the feminist movement started off as a way to get rich white, a VERY specific kind of white, women the vote... or at least that part of it. The sexism they experienced didn't make them any more apt to handle the issue at the time, it actually took a lot of time, effort, and debate to expand it to what we have today. This knowledge wasn't gifted to female or male.
