coldstream, you are making no sense. I'm sorry. I presume the "positive aspects" of Western civilisation you attribute to Christianity are such things as participatory democracy, the rule of law, literacy, education, &c?
Well, the very same people who set those up slaughtered Indians, enslaved blacks, brutalised women, and justified it all in the name of God.
I'm sorry, I believe you are a pretty good person, your hatred which you deny is hatred of gays notwithstanding. But you have fallen into the trap of taking credit for the good things and self-absolving of the bad. Not unlike how so many Christians say we must thank God for the good things in our lives, but cannot blame God for the bad things.
Makes no sense.
