I'm going to blow your mind here so brace yourself: somebody can be in a PhD program and disagree with the premiss of same sex marriage. Someone can be smarter than YOU (absit omen) and disagree with same sex marriage. Eugenics necessarily isn't a bad thing. Women having a lot of sex partners is a prima facie violation of the naturalistic values which evolution has imposed upon humanity. Bonus fact: you cannot have (legitimate) values outside the ones which are naturally imposed.
