Why do females seem to blame men most of the time for "body shaming"?
Body shaming is predominantly a female to female practice. I and most men will tell you that we spend VERY LITTLE TIME talking about women that we're not attracted to. Women on the other hand CONSTANTLY comment about other women's bodies including when the woman they're gossiping about isn't anywhere to be seen.
The problem with women is that they blame all of their problems on men when in truth they're the ones who are always stirring the pot with each other. If you want to find chronic body shamers look no further than women.
