Men and women have equal rights in all western societies.
No, they don't.
We're getting there. But we're not there yet.
Is this your reasoning for why someone staring at a woman for seven seconds or so is not harassment? Because the law says so?
Only a sexist would think that a woman at a game store on the receiving end of a cat-call would be helpless to do anything about it without the intervention of some other authority.
Nobody said that all women are incapable of dealing with cat calls without resorting to asking for help.
That's not the crux of what's being discussed here. (Again, it would help if you'd read the thread, and the various links.)
In terms of sexism, I hope you'll agree it would be sexist to say that cat calls are just part of life in gaming, just as it would be sexist to say it's a woman's job to deal with things like cat calls, no matter her age.
After all, the men in the vicinity--as well as the boys who hope to grow up to be men worthy of the term--should be putting their fellow in place before the woman gets a word in edgewise, even if they don't know the guy.
But that's not what's happening. Enough so that people are speaking out.
And because it's not happening, women feel powerless, isolated and alone.
Why? Because if the men in the room didn't do anything when the cat calls took place, how does it follow they'll back her up if she stands up for herself, much less that they'll have her back if she's not comfortable with confrontation and asks for help?
