Phillyastro hurls the high heat and takes the COTW:
Every civilized person in the West claims they abhor eugenics until their daughter wants to get married.
Parents aren’t the only secret eugenicists. The daughters and sons will find it much easier to fall in love with a person who is high mate value and thus eugenically optimal. God teaches us the power of Love so that we may advance as a species.
Interesting thing about Love. Love can be both a rationalization for a poor mate choice — “oh, but she’s so in love, and that’s all that matters” — and a euphemism for a eugenically pleasing pairing — “it wasn’t his money, it was love that brought them together”. What can’t Love do?
