Let's not.

Answer the question, please.

Unless I'm misunderstanding the bit of legal code he quoted, he did give you an answer. "Most of the men between 17 and 45 years old, plus various others."

...

That's how many are eligible to become members. I asked how many are members.

Incorrect.

You assume facts not in evidence, specifically, that absence of a declaration of membership in a militia is evidence of lack of membership in same.

I will again quote the relevant federal law:

The militia of the United States consists of all able-bodied males at least 17 years of age and, except as provided in section 313 of title 32, under 45 years of age who are, or who have made a declaration of intention to become, citizens of the United States and of female citizens of the United States who are members of the National Guard.

Nowhere in there does it say you have to "join" a militia. You -are- a member of the national militia already.
