The founders were Christian and created a Constitution allowing freedoms previously unheard of in any other nation on earth. Like it or not you have God and our Founding Fathers to thank for your freedom to speak your mind or believe as you wish. I know you hate that but it's true nonetheless.
The first Congress of the USA sponsored the printing of a Bible in the USA and suggested that it be given to the inhabitants of America. The link is in my signature line.
We have Christianity to thank for the Salvation Army, Habitat for Humanity, World Vision, and many, many others. Here in Denver we have the Denver Rescue Mission that feeds thousands of homeless folks each week. They have temporary housing and will help poverty-stricken people get the medical attention than some need.
I realize that you are filled to the brim with hatred for Christ, the Bible, and Christians but if you could wipe the scales from your eyes for just a moment or two you would see that Bible-believing Christians are a great benefit to their fellow man. Just in my area alone I can think of three hospitals founded by Christian denominations: There's a Lutheran hospital, a Presbyterian hospital, and a Catholic hospital. I've yet to see a "Marxist Hospital" or an "Atheist Hospital." Just sayin'.
If you're just sayin', you shouldn't be just sayin' falsehoods. Some of the founding fathers were Christian, some were not. You seem to be confused about the vision of the FF's. They envisioned a long flourishing, pluralistic nation. They knew enough about religion to understand that majority religions are poorly disposed toward competing religions. How interesting that this "Christian nation" as fundies would describe it was established with a muzzle on government interference in the religious matters of the citizenry.
Whether you like it or not, I actually don't have your gods and I'm not forced to kowtow to your gods or anyone else's gods. Thanks to the vision of the FF's, I'm free from your religious beliefs being forced on to the public.
Yes, we have freedom
from religion.
I realize your fundamentalist beliefs cause you revulsion for those who don't share your religious beliefs but you need to understand that there are fringe elements in all religions where extremists find those like themselves.
Fundie Christians also have to accept responsibility for the damage to humanity their religion has caused. From the Dark Ages to Inquisitions to televangelists to child abuse syndicates run by the Catholic Church, religions have a history of death and misery in their wake.
Altruism is not proprietary to religions and certainly not to Christianity.
