Armed Left Wing Militias?

I lived for the past 20 years in southern California. Due to circumstances beyond my control, I have relocated to Texas. I thought I would never live in Texas - especialy being a lifetime union member. Texas isin't just conservative, but actively anti-anything related to the labor movement or working people in general. And the really sad part is that some of it's poorest citizens are actively anti-labor union. It's like a Dicksonian distopia here!
Since I grew up in the south, I can blend in well. However, I have purchased some guns - mostly to relive my youth spent in the woods hunting. I'm looking foward to do some deer hunting. I am as liberal as they come, but I also recognise the need for hunting. There is nothing worse than seeing starving deer in an over populated area.
I recently saw a documentary on the "Weathermen". That was the last "left wing" armed movement. However, I am convinced there are some who feel the need to organize an armed left wing group. Not for terrorist, but for Americans who enjoy their 2nd Admendment privliges. And happen to believe in labor rights, true republican government, and the freedom that our revolutionary forefathers fought for.
What do you think? Is this crazy thinking? I truely believe if the "Bachman" hits the fan, there would be as many liberals with guns as conservatives.
