The number of times I've earnestly seen the take "but it's good for fat people to be mean to them! It motivates them to lose weight!"
Also whenever you provide even light pushback that maybe bullying people does not magically make them skinny but instead makes them depressed, they immediately demand scientific sources as if "bullying fat people is good for them" is scientific concensus and you therefore owe them a peer reviewed paper.
No babe I'm so sorry you're not actually doing people a service by being an asshole to them you just want an acceptable target and have decided that fat people are one. You don't get to be a bad person until you've produced 3 peer reviewed meta analyses that being a dick to random fat people improves their health, OK? I'm sure people will thank you for your invaluable service of being an asshole.
