Body shaming is not just limited to weight. People get comments about their skin tone, height, facial features (wonky teeth/stubby nose), even some unfortunate deformity( even wearing glasses🤓 - Shadi nahi hogi, blah, blah).
Most of the times the perpetrators are our own family and friends. They do it either because they themselves are insecure in their appearance or just don't realise the effect of body shaming. In many cases, they do realise the effect and very much intend it, especially if they are extended family.
It's common to compare between cousins, especially girls, based on their looks. Sibling rivalry too plays a part. One of my aunts looked down upon her sisters because she was fairer. Now her daughters consider themselves superior as they have inherited those genes. Needless to mention they are quite vocal about it, not a visit goes by when they don't insult someone for their skin-tone🤷♀️
