Take a look at this thread that I commented on
I am Gary White.
What do you think?
You can lead a horse to water but you can't make them drink, and a man who changes his mind against his will is of the same opinion still, therefore I tend to think that debates with people who aren't open minded is best to not get your hopes up. If someone really wants to know why you believe (or don't believe) in something they'll really listen to you. If they don't even listen then they have no intention of changing their minds. You are at that point wasting your breath imo.
So in the end they banned you and the other guy from commenting at all, and then had a big old victory circle jerk... I try not to be antitheist, but reading through that really boiled my blood.
