Thanks, that makes a bit more sense.

I'm still not sure why he mentions race when the topic at hand is age, gender, and language, though.

That's easy to answer -- they're all ways to unfairly single out people based on traits that shouldn't be used to distinguish people, ways that are now illegal in some cases -- age, race, gender.

He's saying calling a woman a girl is equally offensive. (Although it's a complete distraction to the discussion.)
