Hating on LGBT folks and trying to restrict their rights is one of those things that is wrong no matter how you dice it. People who believe otherwise are wrong, full stop.
So it's not really so much about people thinking someone else's views are awful. It's about whether or not those views truly are awful. And I feel very safe in saying that if someone thinks my support of LGBT folks is pretty awful, they're in the wrong, not me. And I'm in the right to think their hateful views are awful.
(Yes, I realize how arrogant that sounds, but I have to stand by it.)
I think this is something that transcends politics or culture wars or anything like that. Having these sorts of hateful views are actively harmful to humanity's and society's future. That doesn't mean I think we should censor people (rampant censorship is also actively harmful to our future), but it does mean we need to somehow fix people and shift the culture toward one that lets people live how they want in cases like this where doing so doesn't actually hurt anyone else. I have no idea how to accomplish this, though.
Just because they hate me, though, doesn't mean I can't disagree with their position.
If every racist, homophobe, and transphobe (and others) would stop trying to enshrine their views into law, I'd have much less of a problem with them. I wouldn't want to hang out with them, but I could safely ignore and not care one bit about their views.
We know the answers to these questions for Norris.
He was an Obama birther conspiracist.
He thought gays shouldn't be allowed to join Boy Scouts.
He was a big supporter of Netanyahu.
This aren't things that are even remotely in the same ballpark as disagreement. If someone is using their celebrity status to cause harm to millions or tens of millions, I think we can say a few unkind words about them when they go.
