Is it because I'm not black?

What is up, America? Have you lost all sense? No other country is overrun with so many ethnic groups that it can't function! I'm not saying that we revert to some uber-racist state of being, but why do we keep making it easier for A) people to get citizenship and B) For the foundation values of our country to be undermined? African-Americans are encroaching upon every form of music. I'm not a particular fan of country music, but I don't need awful rap to be mixed with it. Now even rock bands have featured hip-hop artists to "sing" during their songs. I read this article about a Mexican woman who walked so many miles and was ravaged by nature all to come illegally to America--where we gave her free medical care, housing, and practically citizenship just for having a touching story about the hardships of criminal activity. And then, all of these people who are illegal immigrants who are simply overlooked have the audacity to complain about the US and its president. I don't understand.
