Not using "nigger" or "kike" or any number of slurs isn't necessarily political correctness, but the standard should be even-handed, whatever it is.
Where terms and phrases become political correctness is when they serve no real or useful purpose, i.e. calling manholes "personnel access chambers", for example.
If, when defending your support for Donald Trump, and your response is,
"But but but... HILLARY!!!", then you lost the argument before you even began.
