Coming from a black female... From what I have observed from an outsider's perspective is: DO NOT get offended If this does not apply to you. I am obviously talking about the couples who behave like this, who make themselves look this way. From an outsider's perspective:

Cons:

A lot of the time the white men seem to be very insecure about their own masculinity, so disrespect Asian men while with Asian women as a coping mechanism to deal with their own insecurity? It almost looks as though they don't feel confident in their own man hood, so need to compare themselves to another man to feel good about themselves, and they feel they have a one up on Asian males, and so try to validate their masculinity by belittling another man... Because... You know... Compared to black men, white men feel pretty small and less masculine.

Cons:

from an outsiders perspective, a con to this relationship is the insecurity I see from a lot of Asian females who date white men. They almost look as though they feel their partner being white is a status symbol or trophy. In my mind, if you treat someone like a trophy simply because of their race, then in your mind you have elevated them above you and established yourself as beneath them in worth, and set your own people in your mind as inferior to them... This behavior displays to the world that you see your own people as inferior. I see some very insecure Asian females who not only treat their white men as a "step up"(meaning that she was beneath him, if getting with him is considered going "up"... She would never admit to this inferiority complex, though that's what she displays), but also display their lack of racial pride by insulting their own men in comparison to white men... Which, you're Asian, so this is saying you see Asians in general as inferior to white, though you lips aren't saying it, your actions surely display it. You are both Asian, and I feel that when I see an Asian woman insult Asian males, and compare them to another race, she is projecting her own insecurity about being Asian in the form of degenerating her own men, which ultimately degrades her entire race. We call people like this Uncle Toms, if a black person behaved like this. You do not want to be labeled an Uncle Tom. Example... Like if I said I hated brown skin or mocked brown skin men, and poked fun at them or berated them. Well I'm black... And my skin is brown, so obviously if I'm insulting my own men who ARE the same as me, I feel this way about myself. People like this never admit to feeling this worthless about themselves, and can't see how their behavior, not only makes it seem as though they are trying to appease to whites by insulting their own kind, but also shows how lowly you think of yourself.

I was going to list pros... But I think I'll stick to the cons. Because I saw a comedy sketch with this Asian girl poking fun at Asian men, and I couldn't help but think to myself "Now... That's pathetic". I think it's nice for PoC to see how other PoC view them who are outside of the equation... To us... Who are neither Asian or white, it looks pretty damn pathetic. It looks self hating... I think that if another member of your race points you out as being self hating, you deny their claims. But if someone who isn't apart of your race, completely out of the equation points out how you make yourself look and notices the same thing that the people in your race pointed out to you, then maybe it'll open your eyes to how bad you look. It looks bad. Of coarse not all of these couples are like this, obviously. Just like not all white women with black men are selective racist, and not all black men with white women are uncle toms, but I wanted to drop a paragraph here on the negativity I see with their pairing.
