A lot of people seems to be defensive here, and that's….quite sad.
I mean, the least all of us can do is try?
I have preferences. So far I am unlikely to fuck, or go out with people beyond my preferences.
But if I immediately avoid people because of my own preferences-- that is my responsibility alone. That is me being an ass, and people do have a right to call me out on it.
Having preferences is one thing, using that preference to immediately block people is another thing, and waving that preference like you had a 12-inch dick is a whole different thing.
