I didn't really think the first comment of that guy was awful.
The stereotype of an American, blonde, entitled woman is was merely to say that you didn't appear to fit into that stereotype. Maybe you do, who knows? I'm sure he doesn't really know either, but he's conveying a lot of what he wants in someone with that statement I think.
Americanized women, as the stereotype that I think he was trying to portray, aren't self-supporting, strong-willed women. They're narcissitic, empty-headed, materialistic and shallow as well as strong-willed about it. Housewives of orange county American woman. Women who *ahem* dye their hair blonde.
Enh, he's guilty of a poor word choice. He's potentially guilty of disliking American culture, potentially guilty of judging people on first looks too much. Oh wait, this is a dating site where you kinda have to judge someone based on looks, right?
Of course, I don't have any experience with someone thinking I'm a submissive, Asian woman, and I don't like most stereotypical American ideals, so I don't feel connected to the stereotypes he's bringing up.
Suffice it to say, if you were offended by the first sentence a potential date utters, of course he's not a keeper. Some of the other stuff he said was, well, odd, but to be fair, you prompted the discussion further down the lines of stereotypes, so it'd require some pretty nifty quick thinking on his part to come out of such a thing and being able to save face. What can he say, no he doesn't want someone submissive and then prompt an argument about it with you since you don't know what else he could have meant when he used the word American as an undesirable trait? Backpeddle and say he shouldn't have used the word American even though it wouldn't even be clear to him that that was necessarily what got you upset?
