The point is that Ozpin could not have been a Maiden. They're being aggressive with their responses because there was an entire scene dedicated to exposition explaining everything about how the Maiden powers get transferred. It gets kind of frustrating when there are fans who scream "THE SHOW DOESN'T EXPLAIN THINGS ENOUGH" and then those same exact fans don't listen when the show does explain things.

Here, a transcript of the explanation on how Maiden powers are transferred:

Goodwitch: (back to Pyrrha, explaining it all carefully) At first, the only thing that was certain was that the powers were specifically passed on to young women. But as time went on, it was discovered that the selection process was much more... intimate.

Pyrrha: (concerned) ... Intimate?

Goodwitch: As we understand it now, when a Maiden dies, the one who is in her final thoughts is the first candidate to inherit her power.

Qrow: Unless it's a dude or some old hag. Then the power goes to someone random, and our job gets a lot harder.

"the powers were specifically passed on to young women."

"Unless you're a dude or some old hag. Then the power goes to someone random"

In other words, if a Maiden's last thoughts were of Ozpin, because he's a man, the powers would go to a random young woman.

Also, it seems that, when a Maiden uses her Maiden powers, she gains that fiery energy around her eyes. Ozpin did not have that. His powers are most likely from an entirely different legend, like how Ruby is a Silver-Eyed Warrior.
