"A and A" is not a meaningful statement, though; it's a tautology, no? if you exclude those, what do you have?

It's not a tautology, because its truth relies on the truth of A. A true tautology would be something like "A or not A".
However, I address your concerns in the second part of my comment, as "A and A" is derivable from "A", and so is excluded.
