Actually the term is over 200 years old although in different contexts. In the 18th century, the term “politically correct” occurs in the case of Chisholm v. Georgia, 2 U.S. (2 Dall.) 419 (1793). Associate Justice James Wilson, of the U.S. Supreme Court comments: “The states, rather than the People, for whose sakes the States exist, are frequently the objects which attract and arrest our principal attention… Sentiments and expressions of this inaccurate kind prevail in our common, even in our convivial, language. Is a toast asked? ‘The United States’, instead of the ‘People of the United States’, is the toast given. This is not politically correct.” (Wikipedia)
In fact, each group has its political correctness. This is why in shuls that identify with certain factions not only is the prayer for the State of Israel omitted but even the misheberach for the soldiers.
