It depends on the context. If I am having a conversation about something political or something secular, and someone brings up Jesus/God I sometimes get a little uncomfortable, but I just try to digress.
This is an interesting question. My son has a friend that he started limiting his time around last school year because he was a "Jesus Freak" - now, I don't mean to offend the Christians on the board here, but to me, and to my son, that is a person that is constantly talking about Jesus and the end of the world at very inapproprite times. My son had a few religions discussions with him, but ended up telling him that since it lead to arguing, he now considered religion a taboo subject with him, and asked him to respect. Well, the kid is very zealous, and would not, so my son just stopped hanging out with him. The kid asked Friday night why my son finds him so annoying...I lookded at him and said ,"because he has told you several times he won't discuss religion, but you keep bringing it up. Respect that and you won't have a problem."
I hear peopole in restuarants and stores talking about Jesus/God here in Texas...it doesnt bother me at all..unless they start to infringe on me, which with the exception of this kid has rarely happened.
