Why do Republicans ignore racism and never denounce it when it's within their party?

[Mjǫlnir]

Nice list of examples. It shows just how reality-based your claim is.

Shall we talk about how Democrats accepted KKK Senator Byrd using the n-word?

Or about how the Republicans denounced and repudiated ex-Democrat David Duke after he changed parties and won election as a Republican from a district in Louisiana?

I guess you just suffer a form of derangement where you see all kinds of non-existent racism. You imagine all kinds of "code words" and "dog whistles" because you are obsessed with race and skin color, and cannot fathom that conservatives and Republicans don't actually care much about race or skin color - we care about character, integrity and honesty.
