/lit/ - Literature

I'm in a relationship with a writer and I have a question. I'm not posting this on /adv/ because this is a question that relates directly to writers. They would not understand the question on that board. Do a lot of writers have extreme beliefs? The guy I'm dating is nice to me and treats me well. He's also written many books and I admire him for that. But I'm concerned that using some websites like this one may have affected him negatively. He has extreme consevative and religious beliefs which I'm worried could put our relationship at risk. Is this common for writers? I use this site too but not as often as he does. I know of certain writers having unusual opinions but his are so extreme that I'm actually amazed he functions normally.
What is it that leads to authors having these extreme beliefs and how can I change him? Sorry if If I'm being vague. He goes here so I can't say too much. Any suggestions would be lovely.
