Ah I'm so glad you posted this! I've been trying to articulate a rejection of cycnism so it's perfect to have the opposite case presented!

I know it is semantics but it's important. You say "it's not cynicism", "it's just the truth". Cynicism is the belief that everyone is almost entirely self-interested. It squeezes out the possibility of altruism and generosity. Its sort of irrelevant whether it's the truth. So you are cynical.

Love that you've found some joy out of being at peace with your worldview.
