Political correctness

There is an alarming trend that I am noticing among those who want to justify their whatever-phobia, hatred, bigotry....etc. 

An attack on and blame of "political correctness".
"If it wasn't for this PC bulls$&% such and such would've never happened"
translation
"I would like to cast my fears, insecurities and hate on others because they are different than me"

Political correctness means to not alienate, offend or disadvantage a group of people within society on the basis of the way they choose to live their life, their economic status, skin color ...etc. now, some will mockingly say "will then why do we put criminals in jail? That's the way they chose to live their life and we need to be PC and respect that" and get a little grin on their face as they think to themselves "I sound wicked smart". Listen, once someone's rights infringe upon those of another (yours on theirs or theirs on yours) then there is no such a thing as PC in the eyes of the law.
​
The term, more often than not, is used to defend those who consider themselves in the category of "us" against whatever target of their hate/racism/bigotry might be. How? Go back to the example above, the ones that say "If it wasn't for this PC bulls$&% such and such would've never happened" would use this line of thinking after a brown/black/Muslim/Gay/other person does something criminal. They would not use that same line when a big, burley, supposed man hides behind a gun and waves it in the faces of those "other"
