Well, if your point is that an anonymous article of clothing by itself isn't sexist, then I suppose nor does mine, since I was arguing that society conditioning people to wear specific clothing based on their sex/gender was sexist. To get back to my high heels example, a pair of high heels sitting around on the floor, of course, isn't sexist. It could be worn by anyone, no matter their gender. A societal environment that discourages men from wearing them and encourages women to wear them (or often even pressures them into it), though? That is.
You're seriously going to argue that men don't suffer as a result of sexism? Wow. Every single man who does not naturally fit into the stereotypical mold of "real manly man" (which, honestly, who does?) will have suffered as a result of sexism in his life. It's just that said suffering is usually less external and visible than it is for women. Society puts enormous pressure on men to act and appear "manly". To refrain from any kind of behaviour that might make them seem soft or feminine, to bottle up their feelings until they crack,... I'd even say that homophobia is nothing but an extension of sexism and you sure can't tell me men aren't suffering as a result of that.
Emma Watson explained it quite well during her UN speech:
EDIT: And I have not once said anything "anti-Muslim". Are you now going to deny that many Muslim-majority cultures have serious problems with misogyny and homophobia? That's not the religion's inherent fault, of course, (there were points in history when Muslim culture was, in fact, way ahead of Western culture when it came to enlightened, scientific thinking, attitudes towards homosexuality, etc.) but it is the current reality of things (and people in power are abusing religion to keep it that way). Denying it out of some misplaced sense of political correctness isn't going to help anyone, least of all the many people suffering in those countries.
