You would certainly be justified in doing so. The behavior of some on this forum is decidedly un-Christian.
I happen to like a seperate forum for religion. The main forum of FreeRepublic is not a place to evangelize, which seems to be the objection that some have to a seperate forum. If you want to evangelize do it here. If God wants people to come to him, then a seperate forum isn't going to stop them. He parted the Red Sea, a mouse click isn't going to phase him.
I have found the religious forum a great help in my life. It's nice to be able to explore doctrine and beliefs without having to deal with the attacks of people who don't really care anyways.
Everyone knows who the most vocal and strident participants in this forum are. It's often difficult to answer them without feelings of anger creeping in. But we should think of it as a test of our spirituality and try to exhibit fruits of the spirit instead of answering in kind:
Gal 5:22 But the fruit of the Spirit is: love, joy, peace, long-suffering, kindness, goodness, faith,
Gal 5:23 meekness, self-control; against such things there is no law.
Hahaha. ooops...Good point. Amen
