1) No, I am not saying that at all. Your own argument to which I responded should give you the context. Exclusion prohibits [women|singles]. Discrimination lets some in but is biased against them, so fewer get in than in a fair system. Exclusion is often explicit and bias inexplicit, but that's not the salient difference.

2) According to your own first paragraph, the argument did convince you to the extent that it's relevant here.

3) I didn't say that the exclusion was accidental. My argument was that it was incidental. I suppose now you'll tell me that this is also a distinction without a difference. Not to me. I wanted to explain this, but I'm getting very tired of outlining the obvious. You're trying to argue that the club of all women and the club of all married people work identically, because they both exclude [men|singles], but I'm not letting you get away with that.
