That's why I always say, if you feel shame, someone else didn't make you feel that shame, you feel it because you know you did something wrong.  That someone may have pointed out the truth that you were trying to hide from yourself, but it was there nonetheless. That's why skinny-shaming isn't really that much of a thing.  We only claim that it is because of the fats' hypocrisy.  But when a fat insults us, do we really feel bad about it?  Usually not.  It usually makes us feel good since we know we triggered them enough to laughably attempt to insult us.  Whereas with a fat you usually just have to accidentally look in their direction to trigger them, when you were probably really just trying to avoid eye-contact & mind your own business.
