some people argue because they like to disagree with other people, plain as that. others argue because, yes, many have no idea what they're talking about and probably aren't even old enough to vote.
i argue because people make generalizations, they lump things together, they said "all there is to it is:...blah blah blah"...
THINGS AREN'T THAT SIMPLE.
The hope is that all this arguing prompts people to go out and get some backup for their viewpoints. In this process, they may or may not discover they're wrong or misguided. At the same time, this 'pointless arguing' prompts people to look into what others are claiming. This is how it should be. We should all be checking each other. I bet I'm wrong about some things, and I bet every single person here has some wrong information in their heads as well.
Either way, the liberals think they are right and the conservatives think they are right. If this wasn't so we could be under a dictatorship. Be happy people are arguing, for apathy and ignorance are the REAL enemies we should be fighting.
