Speaking as an Atheist and lapsed Catholic:

I agree completely. While religion has a component of belief, it is primarily an identity, that the vast majority of people are born into. Despite not believing in God, in many ways I still consider myself a Catholic (as does the church). The idea that religion is about your personal relationship with God and belief is a Protestant one.

There is a reason why religion is included among other protected classes, but political affiliation is not.

Atheist communities online have a sanctimonious tendency to consider their bigotry above reproach. It's how you get the slide of figures like Richard Dawkins into the right-wing on the coattails of islamaphobia.

There's a fine line between making fun of a belief and stereotyping an entire religious group. And some religious groups - like Mormons or Wahhabists - are deserving of most of the hate they get. But the Catholic Church is not as bad as many make it out to be and millions have been massacred even in modern times over anti-Papistry. Spreading the ideas of Islamaphobia and anti-Papistry kills people.

I think there's a gray area with State Atheist countries. I think the way, say, the DPRK handles it - with the complete outlaw of religion - is not the right approach. In China, religious minorities are protected under the law but not allowed to join the Communist Party, which I think is close to the right approach.
