Just like in Farenheit 451
I think of soccer mom in relatively neutral terms, but my feeling tends to be that it means "she's merely someone with no life for well-meaning but misguided ideas and not because she's outright depraved." Like it's an attempt to say "full time moms: not as bad as we usually think they are."
As for feminism, yes, I know a lot of people who use "feminism" as epithet and justifiably so, though one usually tries to attach some word to distinguish the crazies from those actually helping women; people I know in meatspace usually call it "belligerent feminism". A lot of those people are women! They prefer someone advocating for their rights instead of the people who use it as a pretext to destroy others or win spotlight for themselves; since the latter kind essentially appropriated the word "feminism" in public consciousness, these women decided to disassociate themselves from the movement.
Personally I don't let cranks define words for me. That includes feminist cranks and conservative cranks alike.
"Public consciousness" is worth paying attention to, but I'm not rewriting my dictionary based on it.
Well it’s because that slippery slope that everyone says doesn’t exist actually does. Recall that the original Mortal Kombat caused all sorts of controversy when it was first released (Doom as well). Compare the relatively tame violence in MK1 to what we have now in MK11, it’s what happens when society collectively shrugs their shoulders and says “it’s just a [game|movie]”.
That nudity is still taboo in games and other media is more a reflection of no one bothering to push the envelope like they did with violence.
