There was a study done where they showed toddlers dolls of various races and determined which one the toddlers preferred. Black toddlers overwhelmingly preferred the White dolls.
Their instincts tell them their entire race is less attractive than White people. Even if they haven’t heard of that study they feel it and it bothers them.
3 out of the 4 women in that image did something to their hair to make it look like something other than their natural black afro. The most White women do is bleach their hair blonde, which is at least a feature some White women naturally have.
