Liberals: Isn't it racist of you to ume that all conservatives and republicans are white people?

Is the place you live at not very diverse or something you would have to generalize an huge group of people? I know a lot of people who are conservative and republicans and are not white. Is a conservative republican who is black a racist if he doesn't like the president? Or are only white people who don't like him racist? Honestly, yall bring up race more than I have ever heard conservatives bring it up. Why do yall still have to generalize cons/republicans as white racists and bigots when a lot of them aren't racist or even white?
