50% of the people who ask those questions are trolls, I know of at least 3 different people who just go to random threads asking "is gay optional? is futa optional? is ntr optional? is sex optional? etc."
Would explain a lot actually, like i said, i genuinely don't understand, if you spend a few minutes researching the thing or, heaven forbid, try it for a few minutes, you can see.
When i find a game, book, serie, movie, that kind of things, i always look around, searching, trying to see if it's for me, if i know it's not, i let it go, if i still have a doubt or if i know it's for me, i try it.
Never in my mind ever crossed the thought to ask such simple/stupid questions.
I can ask dumb things, i'm not perfect (far from it), but i at least look around before asking things.
