Heh, thats the funny thing tho. Society isn't changing in the way you suggest. People in general have not suddenly become puritans. The issue is that there is a certain ideology that has become ingrained in education at all levels, in nearly every major media network, and in legislation as well.
The rants about clothing in gaming is not caused by the gamer demographic changing, its is the result of a generation of kids getting their heads filled with retarded ideas in school and now they feel a need to crusade about it everywhere.
Gamers however (you know the people who actually spend their time and money on enjoying videogames), they as always simply likes games that are fun to play. They are also increasingly getting fed up with feminist bullshit narratives trying to muck up their hobby. In fact people in general are getting fed up. Thats why the number of people who identify as feminists is ever shrinking, while the group that does becomes ever more whacky extreme.
