And, while I don't agree with his tactics, I understand that for him this is another game so I understand that raging against him would be just like breaking my mouse because some guy killed me in Counter Strike, ultimately pointless.
"My tactics" is realization that ultimately it is pointless trying to convince someone on any topic concerning politics or religion. You can present all the fact in the world, cite all the studies and debunk any myth but people will simple hear what they want to hear and ignore what you said. As such, there is no way to "win" political argument if you debate cleanly. Best you could hope is agree to disagree, but that is when everyone behaves, and that rarely happens even if you act like a saint.
I use this forum as a test platform to see what are typical positions and opinions for various people (and we have great sample from all kinds of demographics) and more importantly at what point each sees red and start acting truly deranged. It is also important to realize your own limitations, but surprisingly nobody here have pushed me into red territory.
Immediate benefit for me - I have out-there conservative relatives that I don't want to cut all social ties with. At the same time I don't really want to nod and agree with the drivel they pass for informed opinions. As such, I used experience acquired on these forums to push back, but not enough so it created social rift.
