Whatever the reason, it wasn't because his characters were "openly maga and a homophobe and a transphobe," because they weren't. Bruce Lee movies and Texas Ranger didn't address those issues at all.
And in spite of his flaws, it's possible that he had some good qualities as well, or at least aspired to them. So maybe those other qualities were what he looked for in the characters he played.
Doesn't seem like he aspired all that hard, since instead of expressing empathy for people who weren't like him, he continued to be a bigot in nearly every aspect. But sure, if you were a white cis straight guy I'm sure he was perfectly kind.
