So would it be okay for me to be publicly racist if that's what I really believe?.
Advertising your religion is not exactly the same as advertising any other interest or hobby you happen to have. An important part of several major religions (Christianity and Islam, I'm looking at you) involves going forth and actively spreading your belief to those who haven't "seen the light". Maybe it's not what you personally believe, but when you advertise your Christianity you imply that you subscribe to their beliefs, including something along those lines. It could make a non-Christian feel that you believe he should be Christian, and that could be offensive to him.

who cares if its offensive to a particular person. As you said part of the religion involves going forth etc. So by putting it in their sig they are following what they believe in, and at the same time not forcing it on anyone.
In that case, you would actually advocate the destruction of people who have no choice over an accident of birth. That would be evil...
With Christians you're really just talking about cosmology, which I equate more readily with the C#/C++ or Fridrich/Roux debate. People have at least thought about (well, at least they had the opportunity to do so) cosmology and came up with something and there it is, and if you find it offensive then you're probably a little unstable and maybe dangerous (much like the racists).
Basically, if you get offended or violent, then you've jumped beyond mere debate or discourse into something creepy.
