What a strange question to ask what he's done to be mocked for crossdressing?
I've been in relationships before. That doesn't mean I cosign everything my partner does.
And, I don't know, maybe a wild hunch, but maybe they are estranged and married in name only? Maybe she's taken a wild turn recently? I don't know their personal life.
I'm not even defending Byron. He probably is a piece of shit. But he's not a public person as far as I know and hasn't done anything wrong that I know of. And no one in this thread has listed a single thing he's done wrong other than being married to a reprehensible person.
So I don't think he's fair game for mockery at all, and especially not for crossdressing, especially not for things done in private, and especially not by purportedly tollerant people until I hear he's done something wrong, not just been around someone who has.
You can feel however you want. My conscience is clear.
