Where do you draw the line between legitimate fat acceptance and science denialism?

I think it can be taken too far in either direction and I don't necessarily have respect for the so called science behind the BMI scale or what doctors say is overweight.  It has been a while since I've looked into the BMI scale but I'm sure it doesn't take into account different body types and bone structures.
 I know it's a joke that fat people are supposed to use being "big boned" as an excuse for being fat but I know someone who's the very extreme example of being big boned.  His hands are genuinely like gorilla hands and I'm sure no matter how much fat he lost the sheer size of his skeletal structure would make him overweight. 

In terms of fat acceptance in general society though I think there's a good middleground in there somewhere. I think it makes sense to be at a level of fat that isn't stopping you do normal day to day things like getting out a car, walking for an hour, being able to breath normally. 

I don't have a lot of faith in BMI charts either. I'm five foot nine inches, and apparently I can be as light as 160 lbs without being considered underweight. I think that's what the lighter side was. I have never been below 180 as an adult.
