I don't know how people get so set.
I have a belief in God. But I am not so secure with it that I feel capable of ramming it down other people's throats. After all, they may be right in believing that there is no God and I may be wrong.
The problem is that if there is no God I am simply misguided; if there is a God then I have happy landings even after I die. For atheists they are the same on the first count but totally fucked on the second. Safer to believe I think.
Bless me God for I am a chicken! Not a bigot!
