Methinks you don't know the meaning of the word, if you think all humanists are crazy. Let me help:
"Humanism is a group of philosophies and ethical perspectives which emphasize the value and agency of human beings, individually and collectively, and generally prefers individual thought and evidence (rationalism, empiricism), over established doctrine or faith (fideism)." [link]
You basically called all agnostics, atheists, and even religious people who put greatest stock in logic and reason crazy. Good luck with that.
I take it that none of you who have commented so far are parents? Until you've brought life into this world you know NOTHING of what it is to be human. Maybe you've all met the wrong people. We are very fortunate to be humans. At least we can think about the world and what it means. Lots of people lay down their lives for total strangers. No other animal does that. I'd rather be a Humanist than believe in an invisible being in the sky. If we all learnt to appreciate ourselves and others then the world would not be in such a mess.
What? How does not being a parent mean I don't know anything about being the thing that I am? There's more to being human than child rearing. Also, altruism is not something unique to humans; it's a trait that's been observed in many other social animals.
