On one hand, I believe heavily in free speech to the point where as a principle (but not a constitutional thing) I find a lot of twitter and facebook's recent behavior awful.
On a personal level, I think religion is stupid and people who refuse to give service to anyone over it equally stupid(especially since if they were actually following Jesus's word they wouldn't be doing it. There's a lot about not judging and jesus hanging out with sinners in the new testament). I try not to let this affect my policy opinions since I try to be logical not emotional about them but I'm not sure how well I succeed. Religious beliefs do seem to be about the only reason people are trying to push for these sorts of things too.
Another point on a personal level is I would not want to work with someone on something like my wedding with someone who secretly hated who I am. Especially if they were being coerced by the government to do it.
So overall I'm altogether confused about the whole issue.
One thing I am sure of is that I am absolutely against any kind of religious exemption to any law whatsoever. Make the law one way or another.
