I have studied a little history.
I am pretty sure that Christians have killed more people in the name of God than anybody else, Muslims included. (Even giving Muslims credit for 2,998 on 9/11.) And nobody has attempted to force people into a certain religion than Christians either. (All that missionary work?) Therefore, profiling the guy out picketing the abortion clinic every day might be wise also.
There is no doubt that Fund is right, Christians have slaughtered many in the quest for "converts". BUT the difference is that eventually they settled down and for the most part are no longer zealous enough to kill to make their point. And I suspect that there are many FBI dossiers on the anti-abortion crowd for simply that reason.
