We also have things like this:
http://mythcreants.com/blog/five-destructive-myths-perpetuated-by-roleplaying-games/ suddenly about roleplaying games. The thing is that I don't mind if Grognard and his buddies want to play "Rape-barbarians of Murderland the RPG" in their homes, it is only an issue if they have invited a player who doesn't want to play that kind of game and try to force it on them. Likewise I don't mind if some other group plays "TUMBLR equality land with puppies and rainbows the RPG."
I think my issue is that when I hear complaints like these there are claims that even villains should not do things that are "triggering" or have any discrimination in the setting which in my mind is awfully restricting. Besides, dystopia is more fun to explore than utopia. Particularly since the characters can attack the problems in the dystopia and fight the system while in an utopia either there would be no badguys or those would be extremely rare at least. (though a detective story in a "perfect" utopia is often exciting.)
But that is slightly off topic. What is more relevant is that this isn't just "dudebros vs sjws" we also have others who simply hate all "politics and agendas" being "forced" to them in media and other people who may not be part of any movement who simply complain about others liking things that they don't like.
And the thing about "pushing agendas" is really annoying since to those people having a single gay person in a media means "forcing the gay agenda" and the same goes for other minorities and issues as well.
