A genocide in my 'murica?

Personally I do feel that a genocide could happen here in the U.S because of the racial tension that has and will be here for a long long time. It only makes since that people forced to be near people they can't stand start to hate each other. I'm not saying that it is okay to discriminate against a certain kind of people for almost no real reason, but it shouldn't be a crime to be weary of the people that we live with; being paranoid  doesn't help just accept the people you have to live with and that will be that.
