Self-censorship--yes or no

[cosmik debris]

There is a currently active thread in which a member offers a religious greeting. Several in that thread suggested that atheists should self-censor and not comment on the religious greeting. While many atheists take that advice, some don't.

Anytime an atheists post a comment about Dawkins or Harris, the theists jump in with both feet. Should the theists self-censor and refrain from commenting on atheist threads?

So tell me, How do you decide whether or not to self-censor?

And please don't waste time with the free speech argument. We all have the right to post, the question is: should we?
