In Milfy City you don't really have the option to play it your way, rather you have the option to abandon the "main" quest or become a rapist.
Good points in the last paragraph of your post, writing is inconsistent if you play all paths (that or the MC is crazed and deluded, which fits with past Icstor MCs in the old rape'em up games.)
I guess you missed the part where I mentioned I'm not going after everyone and it hasn't stopped my progress with the sisters. I don't see how skipping bitchy side-story teacher leads to missing anything, she doesn't intersect at all with the other plot lines. Just like the neighbors. Your argument that you have to do everything doesn't hold water.
And again, it's your choices in the game, there's no gun to your head, a player who was
honestly opposed to this stuff wouldn't have been able to see it. Going "well, gotta rape to see everything" isn't a reaction a person who was really against it would have. Seems like grasping at excuses for doing things that go against the personas people craft on social media these days. People are doing it all over. Someone might really be nostalgic for the PS1 Tomb Raider game but they won't replay it because that goes against their carefully cultivated twitter posts about feminism. It's ridiculous, there's no connection between what you apply to real people and what you like in mindless entertainment.
