I'm yet to see anything of scale on reddit/voat that represents hate of fat people, and not of the lifestyle or the dumb ideas that the movement comes up with.
I can make fun of my wife and my kids and my friends, call them funny names. It doesn't mean I hate them.
That may be true. But it's also very clear to those that visited the sub that FPH was far beyond just "funny names" and definitely lived up to it's name.
I would completely agree with you if the sub was named IHateFatPeople or FatPeopleSuck.
But my greater point is that we are obviously all okay with negative social stimulus (shaming et. al.) to curb bad behaviors. This is how virtually all social conditioning works and it's part of how we have a civil society. I don't think it's a good idea to decide some negative behaviors should be immune to negative social stimulus. Apply the same rule to everything, one way or the other.

Edit to add: 'yjftsjthsd-h points out that this isn't an apples-to-apples comparison. (https://news.ycombinator.com/item?id=15224303) In this entire thread a lot of people are unknowingly or willfully talking past each other. That's the tough part about heated issues like this. Actually taking the time to break down and listen to each other to understand where we're coming from first—even if we don't agree with the conclusions on the other side—is fundamental to us having a useful, constructive discussion.
Should we have an ignorance acceptance movement, where we don't push people to educate themselves? That's a choice as well.
I'd say that tactic (criticisms and making fun of) worked in many instances.
There are a lot of other things different about Japan (most people walk more and drive rather infrequently, food portions are smaller, the actual foods eaten are not the same, for instance) than just how tactless or not Japanese people are about weight. I bet if you looked at Nikkei with Japanese immigrant parents you would see rates of obesity that looked much more similar to American ones than Japanese ones too.
In addition, although it's a slower creep, Japan is seeing average BMIs go up.
