I also took measures to eliminate my exposure to news and politics. I sold my TV over a year ago in order to escape BBC World because I used to sit in front of the TV crying and feeling useless and upset. It had an awful impact on my daily life and it was somehow addictive.
Nowadays I only hear about politics from my mom, who dreams of getting Bush impeached and who has taken up work in politics again since she retired. I listen to her and I am happy I don't have to be exposed to such things and thankful I don't live in the U.S., where I would never be able to avoid exposure to Bush and American politics. She can handle it, I can't.
Additionally, I used to take part in forums on a different website where politics were a topic of discussion and there were so many fights in those forums and I can't remember one person writing there who was actually writing with the intention of learning with an open mind.
