Accuse the recipient of being a prejudiced white male and make a sarcastic comment about their political views.
Your comments tend to suggest a smug white man. Of course, I could be wrong. However, for more than 60 years I have tended to be good at sorting out white folks. Black people that are not good at that don't live free very long. BTW, I'm sure you are not the only white male bigot. You have all the Trump voters for company.
