What??? A conservative staff in the ultra-liberal media world? Unpossible! /sarcasm That myth has been put to rest on this board a number of times, it's nice to have a corroborating example.
I say speak up! A big part of what is wrong with this country is the inability to have a dialog about actual news events and politics. The No Politics/Religion discussion rule is seldom a useful thing to follow. I've met people at work who came at me advocating a nuclear attack on Iraq who, after many --sometimes heated-- political discussions, were marching in the street with me to protest the war. So opinions do change. There's still that fanatical 30% of Americans who blithely support the current White House occupants and I'm guessing that the vast majority of those people have never been confronted or asked to defend their beliefs. Some people structure their lives (AM radio, Fox news, WSJ, etc.) so they never have to encounter an opinion contradictory to their own.
Invite people over after work to watch Stop-Loss (now on DVD!). Circulate something like
http://www.alternet.org/waroniraq/60950/, and see who ponies up to discuss it with you. Most reporters I know are allowed blog space on their paper's website without editorial oversight, use it to spark political discussion. Confront ignorance with patience and knowledge.
Anyhow good luck and stop biting your tongue!
