I have a few white friends who have married Chinese and Japanese girls. No dramas as the children will be born with even fairer skin tones.

From what they told me its dark skin that is the issue. Even some of the darker skin tone asian girls (darker compared to white people and not even close to a typicalamerican black person) said their parents use to tease them about being dark and that they needed t be fairer or they won't find someone to love them or in extremes give them lotions that supposedly meant to lighten your skin tone up.

Pretty much the norm to see mixed people in California, though of course there are ignorant people everywhere so judgement isn't 100% benign

In my area (hell, in my home) it's fine. Nobody even pays attention to it. I imagine other parts of America might make it a big deal.
The female in the OP is beautiful, btw.

I'm mixed and it's never been an issue for me. (USA, TN)

The biggest issue that I see is that people who aren't used to dealing with mixed people aren't sure how they are supposed to act. There is confusion on what to say and how to phrase things. When people are uncertain, they tend to keep their distance.

Trying to generalize the United States on something like this is useless, though. Even within my state, you'll find the way people think differs by region. Experiences can vary greatly.

One thing I do know is that there are pockets of people who think it is "wrong" to marry those of a different race, a lot of which comes from religion. However, many of them don't treat mixed people worse because of that belief.

I've never seen it be an issue here in Canada (Nova Scotia). I have a friend that dates a white girl and had a half black kid, doesn't seem to be any issue their.

In Korea, almost the same deal as Japan, only a bit more accepting of Europeans, but then again I think it's the same in Japan. In both cases, most look at whites or white-mixed with more curiosity than rasist. But be anything else and be discriminated. Hell, korean-japanese biratial people are discriminated in both countries once people actually KNOW they are biratial despite it being ALMOST impossible to tell apart from either side, and I'm speaking as an (open minded) full blooded korean.

It also doesn't help that you CANNOT get full citizenship in Japan unless you are at least part Japanese. There is a  difference between having Japanese 'citizenship' and being Japanese even by law.

In the west, where the kalergi plan is in full action, intermixed is publicly accepted as the ruling political propaganda. In other regions, this will likely not be the case.

I live in the US where a lot of black people accept mixed people and like you said consider them black. I never really thought about it back then but now personally I think we should really stop doing this especially when biracial people consider themselves biracial and not fully black.

Dude if you use words like "Kalergi plan" to describe European politics, then you need to start taking your meds.
