I remember there was a time when someone on the internet was saying that the classic MK games where sexist because it's possible to pick a male character and beat up female characters. They made it sound like one could create a ladder of nothing but defenseless female characters and beat on them all day... and that's what everyone who plays MK was doing. They must have thought the M in MK really stood for Misogynist.
As for me, I wouldn't mind if the designs where less "trashy".... (which is a matter of opinion.. cultures who are less uptight wouldn't see it that way at all.. and fighters aren't exactly known for completely covering up either)... but some people wouldn't be happy unless they where all reduced to wearing burkas or something... no wait.. just the fact that they can be beat up is too much for some people.. female characters must be taken out completely to protect them.. But then there wouldn't be any which would anger yet another crowd! Like with the recent Assassin's Creed Unity thing.
