I think it's entirely possible to appreciate someone's works while not actually liking the someone that created them. Not just in this case but in general with many artists. I listen to alot of music and watch tv shows, but I wouldn't want anything to do with many of them. Many of them are substance abusers and I really wouldn't like to be around that, for example.
For myself as well, I many times try not to find out about some people's private lives as I usually am disappointed with what I find out, also, it is none of my business.
GR's life is well documented, and I've read through this thread and others.
I love Star Trek, I don't love GR. I don't think there's a problem with that.
