If anyone, when making a rhetorical appeal to you, uses any sequential combination of the words, "racist," "sexist," "homophobic," and "xenophobic", you must immediately disregard everything that person says or thinks, and smash a pie in their face (if you are fortunate enough to be holding one at the time).
The same rule applies to anyone rattling off a list of sacred-cow minorities (black, hispanic, womyn, LGBTQ, etc.) while trying to make some lame social-justice argument. Disregard. Pie in face.
The rhetorical devices that these people use are learned through years of marching in street-protests (instead of working), chanting low-IQ liberal mantras, and waving misspelled signs. Dead giveaways.
You don't have to listen. You don't have to hear them out. You don't have to be polite. The power of "political correctness" shaming is officially used up and destroyed. We don't care any more. Tell them to go pound sand. You've got work to do.
The Christian Right built Western Civilization, and now were going to rescue it from the godless communists that have been tearing it down for the last 50 years. They no longer get a voice in the matter.
