VOTING is a way of influencing your environment. Politics is much more bullsh-- than art, and you can't control anything. I can't speak as to your actions in that forum, but most people that are into politics just like to argue. Don't fool yourself into believing that anyone you have a discussion with online is going to be genuinely open about politics when that can hardly ever even happen in person.
But to the OP, like others have said, pretty much everything online is complete bullcrap. Muscle mags aren't any better. Everybody is just trying to make a buck
