Imagine if the same thing happened in the 60s as we started to understand the risks of smoking - all the smokers got together and decided that the science was hateful and they were being discriminated against. To rephrase a line from the article, using that silly hypothetical:
"In the end, says Flegal, defining smoking by number of cigarettes/day promotes anti-nicotine attitudes and tobacco stigma."
One can't navigate conversations about obesity without topics like "attitudes" and "stigma" being part of the conversation, but I don't think the hard biology of the results of excess fat tissue really cares.
I'm aware this is a bit of a goofy tangent, but hopefully it highlights the silliness of the current obesity discourse.
