[little jeremiah]

Being an atheist with the message that “religion is bunk and God does not exist” is not a religion on a par with actual real religions.

If the above is “religious expression” then anyone can write up anything in the world and call it “religious expression”.

[little jeremiah]

“Religion” means belief in the (a) Deity, not any BS nonsense spew anyone can come up with.

[a fool in paradise]

It is an adamant religious belief that denounce all other belief systems. It is a religion.
