Are all my atheist friends going to kick me out of the club?

First of all, this is the wrong section, and you should have posted this in R&S. Secondly, no atheists won't kick you out of the club or stop being friends with you because you converted to a religious or adhered to a belief. Atheists or any person, whatever he/she follows or believe, will kick you out of his life when you start to shove your beliefs down his/her throat.
