if you would like to discuss politics, religion or ANYTHING feel free to visit http://www.christianforums.com/.
I haven't been there for quite some time now but was VERY active there before. I just signed in to look real quick and there have been a lot of changes, but I am sure it is just as good. There is a place for everything. You can debate (not argue ) about anything (politics, religion, etc...) And no, its not just for christians. They welcome anyone and everyone. They also do not try to convert you. They present their opinions when asked and all. Very good community. Have fun
