Your stance is that cultures are cardinally sortable things, with specific ones being more 'valuable' or 'better,' that you
are allowed to be bigoted toward 'degenerate' ones, and imo you're taking it as a sort of consolation prize since you're not allowed to discriminate based on race.
Just be bigoted on race, man. The richest man in the world does it, nothing stopping you from doing it too. You don't have to hide it in this era.
Alternatively you can think harder and understand that the world is a complicated place, cultures can't be assigned numerical values and sorted, there's more variety within cultures than between them and have all sorts of circumstances and history that explain their situations that go beyond 'this culture is 3.75 eugenic units better than that one.'
