White People: How do you feel a majority of white people feel about minorities?

I’m not sure what I’m looking for in this question. Not asking about the individual minority, but more of the minority cultures in general…

I live in a town that is probably 70% Mexican-American, 20% Filipino America and 10% other (whites, blacks, Guadalajaran’s other Asians all mixed in here)

Anyways, I wondered where the white people that set up this town ultimately ended up living? Of course yes, I understand some people get better jobs and eventually sell their old homes but how could a whole race all of a sudden up and seemingly go?

I hope you catch my drift I’m not trying to stir up controversy. I didn’t grow up with my white side so I’m honestly not adept to that culture. The white uncles that did stay here in South Bay San Diego I realize were a different breed of people with extremely thick skin having all been served in the Navy and they eventually married other minority women etc.

Please don’t be offended. I’m trying to view this question in the form of me asking and explaining to aliens thousands of years from now.
