Cool deal, never even bothered to look for that group! Although I have been somewhat paranoid about what I put on Facebook...sort of been giving that a lot of thought lately. For a bit I tried just cleansing my profile of anything "radical" appearing...then realized how fruitless that was when I still had "radical" discussions with my friends.
Not only that, but I have opened up several of my friends' eyes because of stuff posted on there...it has proven itself effective in that. I've given it a lot of thought, and my current opinion is that at the current time, things are not quite desperate enough that we have to "hide in a hole" about our beliefs. The risk of being under scrutiny looks to be outweighed by the possibility of getting more people to see things in a different light, for me, right now at least. Not only that, but I get to have some interesting discussions with some of my very liberal friends. I've taught them some things, they've taught me some things.
Besides, why should we marginalize ourselves? The louder our voice, the less of a minority we are!
