Dude, if you cannot accept someone is multi-cultural, that's your problem.
You are not limited to being just 1 person, you want to live life outside your own custom and tradition, you can do that with migration, which people has been doing it for the last 2000 years or so, and it is what that for.
I like being carefree and layback as an Aussie, that's why I move to Australia, and being smart as an American, that's why I lived in America, and being honest and hardworking like a Chinese, that's why I lived in China, and being efficient as a Swede, that's why I live in Malmo, if you have a problem with that, that's you, not me.
Again, as I said, I like US Basketball, Australian Rules Football, Chinese Gymnastic and Swedish Handball, Does that make me less of one nationality and more of the other? If you think so, that's your problem, not mine.
