I took at it the other way. In my experience, and I think it's not controversial to claim this, devout (is there a better word? active?) Christians are in the minority in technology context. And especially so in 'tech cities' like NYC and SF. Specifically recognizing some minorities as protected and others as not protected can come across as antagonistic.

Of course that's just anecdotal, but it's worth considering that Christians do feel pressure to 'stay in the closet', so to speak.
