American Indian Scholars Scholarship

How can this be legal or constitutional?
I’m not talking about the Arizona law. I’m talking about this Gates Millinium Scholar thing. This is what I found online:
“Students are eligible to be considered for a GMS scholarship if they:
Are African American, American Indian/Alaska Native, Asian and Pacific Islander American, or Hispanic American”.
This is nothing more than blatant discrimination and racism. How can this be happening? Can’t this be challenged? White people need scholarships too. Can you imagine if there was a scholarship program and you could only apply if you were white? There would be a huge outrage. And this is not the only program doing that, there are dozens of grants and scholarships available to non-whites only. How can this nonsense be stopped? And what about affirmative action? How can employers be forced to hire non-whites over whites? I was actually denied a city (Los Angeles) job soley because I am white. Why aren’t white people standing up for their rights?
well when white people do something for them and to benefit their own race they are considered racist but for some reason society has a screwed up rule that minorities “CANT” be racist… which is stupid because they can be and alot seems like they are….. if white people would have left germany alone in WW2 and let them do what they were doing we would not have this problem.
