If you have a standard or thing you are attracted to, you must be that exact thing yourself otherwise you are a hypocrite.

Thusly, if you are a male with dark hair, and you are attracted to blondes, or say you only want to date blonde girls, this makes you a hypocrite. You are holding her to a standard you do not hold yourself to. You could bleach your hair or dye it blonde, but you choose not to. Yet you demand a blonde wife or girlfriend. You are holding her to a standard that you yourself fail to abide by. This is hypocrisy. You are a hypocrite.
