Was it jokes making fun of him or the flattering meme like "When Chuck Norris does a push up, he isn't lifting himself up, he's pushing the Earth down. "... almost making him into a deity.
Just took a look at his Wikipedia page, and it says he was a supporter of 2008 CA proposition 8, which banned gay marriage. That was a long time ago, but there is nothing in his Wikipedia page after that that suggests he changed his mind since 2008. I think it's fair to assume based on his continued support of the Republican party and their candidates that he has maintained the same view on gay marriage.
