Certain PC terms are simply inaccurate but are imposed on a population to achieve political agendas. Off hand the term "Native American" as it was invented and has been used by the PC crowd is preposterous. People of any racial background born in America are native Americans. The first people known to settle a designated area are aboriginal. The PC use of the term "Native American" is not only misdescriptive, it disenfranchises people born in America as native Americans.
The use of "red state" for Republican majority voting and "blue state" for Democrat majority voting feels counterintuitive to me. I still have to remind myself which is which because the color red has been prevalently used by socialistic countries such as the former USSR and China for many, many years. Therefore when I hear "red state" what comes to mind is "socialistic (Democrat) state". I still have to use "R is for Republican" as a mnemonic device. Language is powerful. He who controls it controls thinking patterns and viewpoints. Obviously the MSM came up with the red state - blue state designations which no doubt shape public feelings to some degree.
