I think you both have a point. Yes there are a few,very few, people who are obese due to genes .
The huge vast majority are obese and sedentary by dreadful diet and choice. Have you seen an obese person in a grocery store motorised scooter with their basket piled high with junk food, paying with a SNAP card?
Many people say they are that way because WE didn't teach them about nutrition.
We should take care of anyone who really needs it including the obese who just made bad choices. For them though there should also be personal accountability required.
