On the screen, he is a character, not him. Not a fan of his actual real life self either, but as long as his films aren't preaching that stuff I am OK watching them.
There is a scientology temple about 3 blocks from me and it was actually my polling place in the previous (not last one), so I had to go there. Pretty creepy cult-y feeling place for sure and I was a bit offended that I had to go there to vote.
