Woah, fella. As much as I'd love to blast Republicans over and over, that's not going to give off the image we want to present. By sending hate, they'll respond with hate. If you want to convince them to change their ways, just get into a respectful and thoughtful discussion.
Also, not all Republicans are racist! Look at Mitt Romney. He's a Republican with honor, and that I can respect (I, myself, am a Lib-Leftist).
And don't blame racism on just one side. Racism is not a political issue. Mainly due to the fact that there are racists all over the board, from Left to Right. Just look at Joe Biden and Donald Trump. Two different sides of the discussion and both of them are racist.
