Hello and welcome Hardervark.
I've always been amazed how the religious folks who have no issues at all preaching and proselytizing their religion, whether on missions to 3rd world countries, banging on doors or passing out their tracts and pamphlets outside sports events can be so put off when an atheist starts to discuss religion, faith and/or god.
Suddenly they get sensitive to opposing views, and want to know how you dare to say such things. Don't you know they will say, that you are upsetting people with such talk?
If you don't believe than please stay quiet...
Stay quiet...or leave.
