You didn't ask that question - I thought your similar question was rhetorical since you answered it yourself. I agree with your evidence that a glass ceiling exists.
If you want to know what evidence I would accept to put this case down to gender discrimination, then any positive indicator not itself based on discrimination. I can't imagine all the possible forms that could take.
edit: on re-reading I see where you wondered about it. The guy coming out and saying it would be evidence, and it's true that even if it were gender discrimination, it might not be at all obvious. That doesn't make it rational to decide that it was gender discrimination when no evidence was given.
No, give me a (some) specific example - you know "If I saw XXX, I would know that there was a glass-ceiling in place". My request is not spurious - anyone that has ever tried to talk about these issues in public gets hit with comments like yours "That's not evidence of discrimination". And each time, on the surface, you're right, you could construct a different interpretation of the events. Nevertheless, when we look at the global situation, you and I agree that our world looks like one in which discrimination exists. Once you accept that as a fact, the onus of proof shifts somewhat in the direction of the person claiming that discrimination wasn't the cause.
