I look at sexual preferences a bit like food preferences.
For example, I really dont like asparagus or sweet peas. (Or raw peanuts)
Why dont I like those things? Beats me-- They just taste unholy gross to me. I cant stand that "sweet but not really sweet" taste they have. its... Its just gross.
Does that make those things bad? No. It just means I don't like them.
Other people can eat them all up, and I wont cry even a single tear.
However, my imposing that view on others is fundamentally wrong. If somebody REALLY loves asparagus, they should be allowed to eat all they want. I just dont want any of what they are having.
My going to the buffet table, and loading up on carrots, broccoli, cauliflower and pals, while strictly avoiding the sweet peas and asparagus is not in any way preventing somebody else who likes the asparagus and sweet peas from eating them as much as they want. As such, I dont see the problem with my not wanting to eat those things.
To me, the problem happens when mom turns up, and screams at me "EAT THAT ASPARAGUS, ITS GOOD FOR YOU!" even though I have tried asparagus, numerous times, and found that No-- No I REALLY dont like asparagus. It's gross.
Further, if, through some unholy power, the asparagus itself insisted that I eat it and that I like eating it-- or else I am a bad bad person-- that would be the pinnacle of No, Not cool bro.
A person's sexual preferences, and as such, their implicit anti-preferences, are not things that have a moral imperitive assigned to them. So what if somebody doesnt think transwomen are the hawtness? It just means somebody else can date that perfectly acceptable transwoman. That's all it means.
When you start trying to make it political and assign moral imperatives to it, you go too far. Saying something like "Refusing to eat that asparagus is hurtful to asparagus eaters, and you should feel bad because of it!" is just plain silly. Likewise, saying something similar about not wanting a certain kind of partner is equally silly.
Thinking that it somehow ISNT silly, and basically forcefeeding people that dont want to eat asparagus those horridly flaccid green stalks of saccharine and telling them that not liking them makes them worse than dirt is every bit as harmful as trying to "Recondition" gay people, on the intellectual front. (I am not saying they do equal amounts of damage, only that they are equally bankrupt.) All you are doing is forcing people to have a neurosis, AND to think they need to live in a way that will not make them happy, to satisfy some silly idea.
It doesn't matter what the preferences are. They aren't wrong, if the person stating and holding them is true to themselves.
Forcing a specific thing on somebody else is always wrong. Doubly so when there is some ideology that is not shared involved-- be it christian conservatism, or rampant political correctness.
Me, I dont like anything at the buffet.
