Didn't you say you're some kind of secular humanist? Regardless of the label, my question was supposed to be about how you would summarize the secular humanism you subscribe to, and you sort of dodged that question. Are you saying you're neither nontheistic nor a liberal humanist?
Your account of secular humanism is pretty paranoid, right? You're foregrounding the conservative's misuse of the label. I wouldn't deny that conservatives exploit labels for their nefarious ends. On the contrary, I've written numerous articles on how conservatives are experts in waging that kind of culture war (whereas liberals are mostly incompetent in that respect).
But besides the formal organization of secular humanism, there's a liberal secular humanistic culture, especially in wealthy, technologically developed, individualistic societies. That culture is looser than an organized religion, but there are common humanistic beliefs which those manifestos tried to capture. And my question is whether your kind of secular humanism differs in important ways from what's specified in the manifestos.
