Satanism is a faith. So is it's close cousin, Statism. islime is an unholy melange of the two - an exaltation of the brutal AND a system of government. I see no reason NOT to criticize these faiths and insult insult followers of same.
Yes, you are correct. I had forgotten about the worshippers of Satan. Poor souls. They are doomed.
As for Islam hating, I wonder what Jesus would say to you about such hatred in your heart. We lived in Saudi Arabia for five years (working for ARAMCO) and didn't see that kind of hatred of Christianity that YOU hold for Islam. Not a particularly Christian attitude, IMHO.
However, you are certainly free to fill your mind, soul and heart with hatred. YOUR choice. Satan must be chuckling at all that hatred you hold on to. YOU think it's okay to insult followers of that faith. Shame on you.
SO Christian of you...(Sarc.)
