i know you're saying it in jest, but maybe not being able to immediately spot the odd or not-so-odd or whatever group a person belongs to is a cultural evolution for the better. it's nice that we can't so easily spot the weirdos. i'm fortunate to have made friends of potheads and drug dealers and Goths or atheists (i'm not lumping them all in, now) or whomever that in earlier times i might have just avoided to my own disadvantage.
