No way...if the pot is black and the kettle is also black it is considered pc for the pot to call the kettle black. Please brush up on acceptable name calling.
Now when a Right Wing fundamentalist (who scratched his way out of the trailer park to become a nouveau riche salesbot) calls a democrat living in a shining urban city a "libtard", that is just not acceptable. In fact we urbanites don't like hearing from Right Wing Red State Trailer Trash, ever.
Gosh, I know that was not a pc statement. All this exposure to trailer trash has taken its toll. Note to self. Must get another job. Must get another job.
Sorry, you are only partially PC here: if the pot AND kettle are black, they can call each other black. Or even use the "N" word, especially if they have just successfully completed a sporting activity together.
If one is black, and the other copper, both can use "black" as a descriptor, unless the copper utensil is a conservative, in which case it would be considered a racist container to use "black" to describe the other. Also in that case, the copper kettle or pot would be described as being "white copper".
However, if one or the other is not black or copper, and is white, off-white, or light tan, the descriptor "black" or "copper" cannot be used at all. In that case, it is PC to use the country of origin for black or copper container, followed after hyphenation by the "American".
You are also missing a few additional identifiers of a conservative. I know, the trailer park connection is very valid, but lets not forget many fine liberals, and more importantly, unregistered Democrats, also reside in trailers.
Here are a few foolproof ways to identify a conservative (that's more PC than "right winger):
1). Posses a gun
2). Allows their children to play with toy guns; does not reprimand their child for using a thumb and forefinger, or a carrot, or other object, as a pretend gun
3). Has an American flag on their pickup truck, or a bumper sticker containing the word "America" in it
4). Has an American flag anywhere in their home, of any size. Even in a draw.
5). Served in the military, and is not ashamed of that
6). Uses the work "god" in any way, except in the phrase "god dammit"
7). Has a copy of the US Constitution in their possession
8). Has ever willingly read the US Constitution (being forced to do so in school does not count)
9). Holds the belief that the US Constitution and the Bill of Rights is anything other than a quaint old document, written by racist old white slave holders, that is no longer applicable
10). Makes a distinction between legal and illegal immigrant
