This is true, but those games were noted at the time for being crude and offensive. There was actually quite a bit of dislike for all of the above, and they were seen at the time as the exception rather that the norm.

I can think of the occasional bad-taste joke in an adventure game, but I don't think it was ever as pervasive as is implied.

That's just some very obvious examples. It's not the only examples.

Duke Nukem is an obvious parody. And most ironically, the franchise always seen has more female fans than comparable genre games.

What do you mean? Would parody exclude the possibility of down-punching? Imitative mocking is always OK?

EG robocop showed lots of police brutality, but it wasn't a movie about how great and normal police brutality was.

You would need to be more specific than that.

It's not even a question of it "indicating" acceptability -- being a fan of something is "acceptance" of it.

Your argument being?

Hail to the king, baby.
