Vivek Ramaswany is the most upfront one that comes to mind. He put himself in a situation where he was openly disrespected (to his face) by Ann Coulter because he wanted to be in a position of power that has traditionally been held by white men, and there have been a number of Black Republicans that people openly disrespected ( or forgot about the existence of) once their usefulness to the Party (basically putting a Black man's face on white nationalist talking points) has concluded.
