Not being able to understand the difference between excess muscle and fat is not semantics.

BMI is a tool applied to populations, used on individuals it can be very inaccurate, which is why nobody does it outside of blogs and magazines.

The term "overweight" does not differentiate between muscle and fat, plain and simple. You're wrong.

You're wrong. The typical diagnostic method for overweight and obesity (BMI) does not differentiate between muscle and fat, because mechanisms that do are too expensive/complex for the use, but the term, in fact, does.

At their most basic, the words “overweight” and “obesity” are ways to describe having too much body fat. [0]

Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health. [1]
