Pointless Bickering

Pray, do tell. Is there any point whatsoever to the right and the left debating and trying to put each other down 24/7? They spend so much goddamn time trying to get one over on the other, that the real issues become obscured by the debate, exaggerated by the media; "Who is best, the liberal left or the wacky right?"
I've noticed this recently on a forum I frequent. Every topic seems to transform into a debate of whether the left is better than the right or vice-versa. Take, for example, a topic on the war in Iraq. One person comments that Bush should be tried for war crimes, and the more conservative members of said forum jump on him/her like rabid animals, shrieking "YOU CAN'T SAY THAT, SHOW ME PROOF!" Each camp effectively tries to undermine the image of the other, claiming each other to be childish. Alas, they don't stop to consider the fact that their pointless bickering makes them both come across as angsty five year olds.

This also applies to the political domain, though thankfully not as extreme. Still, instead of debating policies, why don't the right and the left try to find a solution that is mutually beneficial for all parties concerned, and especially the public? That way pretty much everyone is happy, right? Or wrong? In a world full of contradictions nothing is certain.
