I don't know much about that, but the answer is always separate the art from the artist. I watch the show because it's funny, but I don't take it too seriously. I had to leave the rick and morty subreddit years ago because of how insufferable the fanbase is and I've enjoyed the show much more being away from it.

Plus, Initially I found the show because I liked Dan Harmon's other show Community. He was the draw for me, not Justin.
