Right now I'm in a "won't lie if they ask, but I won't come out and spout it" stage. So far, no one's asked. The worst they assume, I'm guessing, is that I'm a backslidden Christian who doesn't go to church. In a way, I am more bothered by that assumption, because it makes me look bad. But since I'm anxious about debating and confrontations (just my personal nature), I avoid bringing things up that will definitely rattle the cages.
I know over time I will be more forthcoming. If I didn't work for a Christian company, I'd be much more public by now.
