Check out Homeland (season 4 episode 1). While I don't endorse violence against fat-shamers it's strangely satisfying to see it done dramatically.

IRL I don't approve of violent responses to fat-shaming, but still enjoyed the scene in Homeland (season 4 episode 1) where a CIA operative beats up two guys who fat-shame his girlfriend.

I think you did great. I can't think of anything you could have done better.

Kudos!
