Please be warned and advised that the strongest debates on AF occur here in the Political forum.
There are extremely opinionated individuals on both (or even all) sides of most of the debates.
Although emotions can run high when debating something that you feel strongly about, remember that you are not debating someone else's intelligence (or lack thereof), background or location, but rather the topic itself and their position on the topic.
For best results

try to back up your assertions with some sort of evidence, and also be prepared to have others find evidence against your assertions and shoot holes in what you have said.
Personal attacks will just get threads closed or worse, so avoid attacking the messenger and stick to attacking the message.
Enjoy the war, er, I mean the spirited debates to be found here.

Oh yeah, and an Internet troll, or simply "troll", is someone who intentionally posts controversial or contrary messages in an online community such as an online discussion forum or USENET, with the intention of baiting users into an argumentative response. Don't be a troll.
