Let's see what Jesus himself says about your sort of meanspirited judgements;
Jesus;
"But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
(Matthew 5:22)
It's too bad that those who cannot defend their postions have to resort to juvenile name-calling and personal insults. And then they misrepresent this as "Christianity".
