On another note, religious beliefs give people hope and if you take that away then you make them depend on the government for hope alone which is sad.
there’s a reason why all the communists promoted atheism.
“If it is going to be a religion free thing at the government level then that means no atheism either on a public bus.”
I just googled restrictions on metro advertising and it had nothing on religion or nonreligion. Restrictions were on drugs, alcohol, obscenity and the like.
I don’t know about the London advertising, but in DC the group sponsoring the ads is American Humanist Association. While the organization has atheists, it also has agnostics, and who knows what else. Their position is that belief in a specific religion is not necessary to promote good, worthwhile behavior. I doubt that the ads are being run because scientists are begining to feel they are on a slippery slope. Rather as the extremes of religion are seen more and more, they are appealing to people who want to be part of a group that celebrates and promotes the good aspects of humanity, without contamination by religious extremism.
The ads are specifically an effort to let people know there is an organization that they might like to join which has similar values and viewpoints.
