Well, the thing with opinions is that yours is as valid as mine. You think it's an issue, and you are allowed to think that, and you are allowed to compaign for it to be changed, whereas I do not think it is an issue, and likewise I'm allowed to think that. As for campaigning, for me it's pure apathy. I wouldn't be bothered either way. If they change it because they think you are right, then great, but if they don't, then no skin off my nose.
Nobody's "policing" anything. I don't even know why you would think that. Bellissimo is perfectly free to express his or her desire for change here, but because this is an open discussion board everyone else is perfectly free to say how they feel about the subject (within respectful reason). I don't begrudge Bellissimo for thinking the security guards in-game are skewed in favour of men, but I don't agree that the term "sexist" is valid here, mostly because it implies intent.
