Actually, oddly enough, I agree with you.
Go ahead and make your Aryan Nation Land or whatever you want to call it as the rest of sit back and watch an Epic Fail or all Epic Fails occur after you form your land.
Then, maybe, just maybe, you will understand that:
1.) Nobody is really loathing over not being able to breed with you all to include intelligent and sane white people, and nobody would want to "steal" your genes as you put it if they had to.
2.) Crimes happen because of social problems such as lack of education or job opportunities, substance abuse, and disfunctional upbringing and living, but not different races living together.
I know, some of you want to point out countries with few minorities saying they don't have as much crime there because of it. But I ask you to look at how their economy is fairing and why the few minorities that do live there aren't causing problems like you say they would supposedly by nature.
3.)I would love to see what type of government you set up, because the last time a government tried to make a pure aryan white land for all whites didn't last for long. And judging from your stubborn attitudes, you all would probably have a hard time setting up basic rules for everyone to follow by.
