Not true. I used to hear white people all the time make fun of people that were pale, freckled, red, pasty, etc....
you and @Tommy Knocks are both right and wrong. white isn't necessarily seen as negative, but a lot of them don't want to appear pale, freckled or sunburned like @The_Sheff said. they have their own colorism issues but its nothing like whats going on with us.
