I know very well that preferences exist. I acknowledged a few pages back. Yeah, preferences are a thing. Like I said before, I hate chocolate covered cherries, those chocolate cordials are absolutely abysmal to me. However, am I going to go up to someone and tell them how much I dislike them to their face while they're eating them? No, I'm not.
The preferences themselves are fine, nobody has to like the same thing. I'm not against people having preferences. It's using those preferences to justify being rude where things get eyebrow raising.
The viewpoint "I personally don't like ____ " itself is fine.
The viewpoint "I personally don't like ____, I hope it ceases to exist/doesn't exist at all, and I'm going to make sure everyone knows it." brings motive into question. But I suppose one could easily write it off as jerks being jerks.
I'm gay too, dude.
