Body shaming is something I don't really like, though it is can be fun with friends ;)
The thing with self-love and personal acceptance is, can someone that actually loves themselves be body-shamed? Does a dog-lover stop loving dogs because a cat-lover says dogs are stupid? Everyone has preferences and opinions, so why get so upset when people disagree?
While I talk a lot about other people, the focus is actually on me improving my own thoughts and behaviours through reflection. I see myself in others more clearly than I see myself.
