My tip? If you do not like confrontation then try and stay away from any of the 'hot' topics for a little while until you become more comfortable here. Anything regarding rape, abortion, politics, any -ism's etc is going to attract bolshy people (I guess you can include me in this list hehe) and things get heated so quickly.
If you don't take things personally though and enjoy a heated discussions then jump right in anywhere - otherwise maybe stick to some of the lighter threads for awhile!
