Let's humor you and pretend this is a good example of what you're preaching. What the hell is wrong with designing characters that appeal to a demographic? If mostly straight men are going to play Street Fighter because men gravitate towards fighting video games in general, why not design it for them?
Lesbians can have their own fantasies. Nobody gives a shit. It's only a problem when they demand they get to have their fantasies and ALSO remove fantasies that are not targeted to them.
