It sound so corny but what happen to live and let live huh ... I mean if you know the spirit of God and you feel it .. that is enough .. sure does for me .. No one that is a non believer or other believer or their God or non God threatens me in any manner. When someone knocks at my door and I am annoyed I say no thanks I have my belief and it works for me just fine and leave it at that. There are very good things about faith, and very bad things done in the name of religion .. mainly because like you pointed out they don't understand the teachings. if they did understand the teaching they wouldn't do those things ..

In any event, being told what to believe or not believe sets people off in a non positive manner. I guess that is why my mom always said stay away from religion and politics
