> Well, then it doesn't much matter which definition of merit (who is better) you take

Yes, it does.

The definition of merit is necessary to assess whether the current system is, excluding AA, actually meritocratic, as claimed. While it would also be necessary in order to assess whether one race or another was better than another, if that were an interesting question to answer -- the fact that I'm not asserting that one race is better doesn't alter the fact that an actual definition of merit is necessary for the claim that the existing system (but for AA) is meritocratic to even have meaning.
