I think that’s just more examples of it being misused. BMI may be useful to compare populations in certain instances. It has value in being easily calculated based off data that is often easy to obtain. But, there are many situations where it would be inappropriate to use BMI for statistical comparison. That doesn’t mean it’s entirely useless.
The criticism of this news is needlessly toxic. Maybe Hamas won’t accept the offer, but that doesn’t mean it’s not a genuine attempt to save some children’s lives.
