That is, I'm afraid, a complete strawman. I don't care where the concept comes from; if it's a good concept, then we apply it. Are you saying that freedom of/from religion and freedom of thought and expression is a bad thing or something that shouldn't be applied wherever possible (there are limits, of course; there are rightfully laws against hate speech and the like, but I'm talking generally here)? If a concept or way of thinking is harmful or bad, I reject it. And the suppression of freedom of speech and freedom of thought is a bad thing. I don't get why people are acting like this is a relative thing.
Also, what Beorning said. I agree whole-heartedly.
