I was not saying atheism advocates for freedom and anarchy. Atheism isn't even a real belief system, it's the absence of a religion belief system.
The issue is, mocking people's religion does hurt other people. You're actively going against what you espouse you believe, which is kind of odd.
Furthermore, many religions can help people contextualise reality around them in a way that is more manageable for them, which builds a community of like-minded individuals. Sure, I don't necessarily agree with any religion, but being 'right' isn't really what's important all the time. Sometimes it is about what 'works' rather than what is right. And for some, religious spirituality assists them. All the power to them, I say.
