Evaluate people by mind patterns, not form
If you’re in a situation where you interact with someone you find physically interesting, ask yourself how you would interact with this person outputs if he/she was ugly
“I have a dream,” said Harry’s voice, “that one day sentient beings will be judged by the patterns of their minds, and not their colour or their shape or the stuff they’re made of, or who their parents were. ~ Eliezer Yudkowsky
