You can take the words and use their individual meaning to come up with any definition you like to make any argument you like. However you don't win arguments by arbitrarily definition words or phrases to be what you would like them to be. You definition factually is not the definition of political correctness. As such historical racism and sexism were not political correctness.
> Political Correctness- the avoidance, often considered as taken to extremes, of forms of expression or action that are perceived to exclude, marginalize, or insult groups of people who are socially disadvantaged or discriminated against.
> In 1934, The New York Times reported that Nazi Germany was granting reporting permits "only to pure 'Aryans' whose opinions are politically correct".[2]
The definition you read there is just what is politically correct today, it isn't what the term really means. Racism was politically correct back then, it isn't politically correct today.

Aren't you taking an arbitrary definition (un-sourced from google/Oxford Language) to win your argument?
Here is Merriam-Webster's
> conforming to a belief that language and practices which could offend political sensibilities (as in matters of sex or race) should be eliminated
Seems like both are acceptable modern-day usages... like other terms a difference between capital vs lowercase might help here like... "republican" vs "Republican", "democrat" vs "Democrat"
