Sure that is true. But any public debate always reduces a topic to its least complex form.

The core question really is: do meaningful biologist differences exist?

I see this as a scientific question, it has metrics, and we already have the answer. It is yes.

From there you can have a discussion about the nuances, but in regard to those people who do not believe the answer is Yes, there's no more point in validating their arguments than those of creationists or communists. Sometimes they'll bring up interesting perspectives maybe, but they are basically just wrong.
