He's always held these opinions, he just hid them among other opinions that weren't as noticeable because he spread the hate around, and mostof the jokes were funny.
This is the same guy that got on his show, and had a segment where a white girl sang his words for him. If you can find the clip without using a service he profits from (I can't right now, it's only available in little "shorts" on YouTube), the whole thing is just him saying shit he doesn't like, that would get his ass "cancelled" if he said them. And the longest segment is about gay sex being gross. Trans issues weren't as visible back then, but the guy has always said this type of thing.
But for some reason, he's stopped doing it to everyone, which is what made it acceptable. He didn't spare any group, but he also didn't target any single group more often than others, except perhaps black people. And it's always acceptable to joke about your own group.
Now, he's just being a douche. The jokes aren't at all funny unless you find it funny to just bash people with no attempt at humor. It has gone far past the kind of abrasive, but exaggerated hate he used to use, but it isn't something new.
