My niece stumped with with a question: Why is the Republican Party allowed to even exist today?

"Aunt Judy, why is the Republican Party even allowed to exist today? Everyone I know thinks that its a racist party that only helps white males."

I'll be honest. I could not come up with an answer that justifies its existence, based upon the reality that the party is the manifestation of our country's white supremacist founding, in fact the "discovery" of the continent by white supremacist murderers and rapists, and that Europe itself oppressed the rest of the planet throughout history under a blatantly destructive Jedeo-Christian philosophy.

If anyone can come up with reasons that the Republican Party is not inherently racist, I and my niece are all ears. In fact, I will be helping her on her term theme paper on presenting why the Republican Party should not be allowed to exist.
