If someone calls you a racist, ask them why. Are they calling you a racist because of your color/religion/economic makeup? Are you calling me a racist because I am a Catholic? Why do you hate Catholics so much? Are you calling me a racist because I am white? Why do you hate whites so much? Is it just pure hate or are you a racist? They did not call us communists because we were not. I am a capitalist, I cannot be a communist. I can be a racist and call you a racist though. The first is mutually exclusive, the second is not.
Liberals call conservatives racist for the political gain. That’s it, nothing else. To respond defensively using logic isn’t effective. It can’t work. They don’t care about logic or debate. It’s just name calling.
