Many people on this board, pagans or whatever, have had extremely negative experiences with people who styled themselves as "good christians". This is bound to leave a few scars. I've been screamed at on public transportation and threatened on the street corner simply for wearing a symbol of a religion different from theirs.
I know some very wonderful people who are also Christians - one in particular who "puts the 'fun' in 'fundamentalist'", and it bothers me to see people be just as hateful towards those who they perceive as being part of a group that was hateful to them. I understand it I guess, but it still bothers me. I just try to be better.
And I sent out cards this year that said 'Seasons Greetings" with handwritten notes that said either "Merry Whatever!" or "Merry Everything!".
