Understood, and fair enough. However, it would've been much more helpful if you'd just said that to start with, rather than answering her with a sweeping dismissal.

I think it's more helpful to sweepingly dismiss sweeping, incorrect generalizations of people that others may take to heart.

I took the "something wrong" part as meaning "you have characteristics women in general will find undesirable" or "you lack characteristics that women in general will require" -- and I see that as a true statement.

I don't, except in the tautological sense ("there's something wrong with men who don't know any women, and that something is women find them undesirable, because they don't know any women").

If you take this as meaning there is something morally or ethically wrong with you in some absolute sense -- as opposed to merely "wrong" for the result you desire -- then I could see how you might consider it prejudice.

Ah, I see. You're talking about "wrong" in the sense that it's wrong to have gay friends, if you want to meet Christians.
