I've always seen BMI for males and females, so how is that racist just because fat LGBTQ don't like it? Is it that trannies don't like going to the correct BMI tables for their biological sex?

Trying to quantify something we all instinctively know when we see it.

Because there is no such thing as fat white people?

BMI isn't a very accurate metric for males if you have any sort of muscle mass.
