Read the FR Homepage. The part about 'Champion causes which further conservatism in America'. You'll note it doesn't say 'moderate'. Or 'prostitute conservative principles just to 'win' an election'.
And since you're a relative Newbie yourself, maybe you missed the Bug Zapper threads where scores of 'moderates' (liberals) got the zot. Many were looooong time Freepers too, like from 1998.
Do you really want FR to become a forum only for those who pass a litmus test to determine who is a "true conservative"? I agree that lefties from alternet trying to stir up trouble here are not a positive addition, but for moderates, mainstream conservatives and far right wingers to air disagreements is healthy for the this site and our party. It's truly pathetic that I get labeled a liberal every time I post something that is even slightly outside of the extreme beliefs of some ultra right Freppers.
Dammit I have Boston liberal relatives who hate me and haven't spoken to me in years because of my views and it is intensely ignorant for some people to blindly insult me with that term if I dont fall in line. I thought the intelligence level was a bit higher on this site so we could disagree and have a substantive debate without slipping into a moronic name calling contest.
