I do not agree. I work with a number of Atheists and they are fine moral upstanding folk.
Hi RA! I realize that there are people who claim to be atheists who are very fine moral upstanding folk.
On the other hand, I submit as evidence the folks who bring us MTV, VH1 and the politically correct favorites, the homosexual activists. I shouldn't have been so surprised but I found that they had a sex club set up in my kids brand new high school from the day it opened 3 years ago.
The agenda is the usual "sexual experimentation for the kids" and "don't condemn homosexuality until you've tried it."
I also submit for evidence "post-Christian" Western Europe. While they celebrate their "liberation" from backward religion, they've embraced sex with animals, sex with kids, nudity in public entertainment and advertising, (best Yul Brynner voice) etc., etc., etc.
At the same time they've neglected to remember to reproduce. Maybe the Eastern Europeans will colonize their countries, but the Muslims could win control through their ruthlessness.
