I think we all prozelytize to an extent. Why I find Christians' doing so offensive. Maybe just because they're damn good at it /sarcasm.
I was in a department store shopping, and a couple of youth approached me and stated they were "moved by the sight of me" and asked if they could pray for me (I'm physically handicapped, missing nine fingers.) If I didn't feel bad about my disability to start, they weren't helping me any. Truth, I'm not even conscious of it 99% of the time. But they thought it useful to point out that they thought I was a pitiable sight. (The DSM needs to be revised to NOT ro mental illness if it is consistent with common religious beliefs.)
Anyway, Christians and Muslims just have a unique gift for being offensive.
Granted, I'm so close to atheists on most things that this is my bias which prevents me from seeing atheist offenses, but I'd talk to an atheist about religion for a year and a day before I'd spend an hour stuck in an elevator with a prozelytizing Christian.
