Their official policy was that if you were ever fat, at any point, you were not welcome and worthy of ridicule.
If you find that motivational as a fat person, I think you might have a different problem altogether.
The social cost of the negative outcomes of ridicule directed at obese people - lifelong stunted self-confidence, eating disorders, depression, suicide, etc. - FAR outweigh the few cases where people like yourself might find this productive/helpful.
Do you really believe that ridicule is a reasonable way for society to deal with this (or any) issue?
Isn't that exactly what's going on with the backlash against hate groups? Like it or not, ridicule is an effective social tool for behavior modification.
S.Korea & Japan are in the lowest three obesity rates for a reason. (Third being Italy)
Aggressive social conformism is just everyone disagreeing with you, loudly. It's the kind of thing we should be doing to racists, etc.
The response was downvotes and "nope, all fat people are human garbage and should be mocked."
Was done with the subreddit after that. It started as a activist subreddit challenging the "love your body" movement that was trying to propagate unhealthy fat acceptance, it ended as a hate subreddit. Shame.
