The funny thing is that basic genetics disproves the first one. Gay people, for the most part, do not pass on their traits to their offspring because they don't have offspring. It is literally antithetical to natural selection.
Which means that there is no way for it to have been an inherited trait, because if it were it would have been filtered out of humanity by now.
So if it's not inherited, and it's definitely not because it literally can't be, there's only one thing it can be.
Like red hair? Red hair is being bred out of humanity just over the last two thousand years. At one point half of Europe had red hair, and now it's vanishing.
For a recessive trait to appear in an offspring, both parents would have to have had a copy of the trait. That happens less and less with successive generations, until eventually it vanishes.
Clearly, being gay is mostly learned behavior, not hereditary. If your father is gay......... is he your father? He could be, but homosexual behavior is learned, not hereditary
"Confirmed bachelor" has been a thing since William the Conqueror, is the thing. Historically they didn't really reproduce in numbers sufficient to pass the trait on.
And even if they had, it doesn't explain the sudden outbreak of it in the last half century. Only an artificial trend can do something like that.

I know a gay couple that has a kid, and one of them is the biological father. Egg donor plus surrogate mother gets it done.
A general rule does not preclude an outlier, and vice versa.
