I usually use "Auf Wiedersehen" which means "See you later" in english. However I don't see the Problem with "Goodbye". Just transfer the meaning to "God be with ye, he sure isn't with me".
I also always though atheists are more tolerant than religious people. However than I discovered the internet and it seems there are just as many atheists, who want to show that there is no god, as religous people who want to show that their beliefs are right.
I have nothing against religion as long as nobody forces me to waste time with someone who doesn't listen or talks to us and whose last action was app. 2000 years ago.
