It was shoved down our throats by education k to C and all kinds of media pushed by the progressive/liberals, google it...
PC was adopted by the US military in 1948.
Would you happen to have a link, I'm curious to see if they used the term PC in 48...
no because they did not use the term then, it was called desegregation, professionalism, honor and a military code of conduct. If you have ever served in the military you must watch how you treat fellow service members and the way you speak to other military members.
