Even if they were a 'cult of sexuality' - what exactly is the harm here? I'm always struck by how, even on HN, there is a current of moral busybodies who, often without understanding the topic or subculture, deem certain activities outside the scope of toleration - even those activities which do not cause harm. The justification is usually rather weak too if not backed up by some religious principles.

The sibling comment refers to "escapism" (as though this is always a bad thing, we should chuck out fantasy and most music too) and "infantile behavior" (citation needed, even if this is a thing we should not tolerate).
