If you Google “political correctness” you find it defined as, “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.” or another one similar, “A term which, in modern usage, is used to describe language, policies, or measures which are intended not to offend or disadvantage any particular group of people in society.”
Those are the Looney Left definitions and they’re completely wrong. Poliitical Correctness is a tyrannical form for speech and thought control. It’s meant to do just the opposite of what those definitions claim, i.e., it’s used to marginalize anyone who disagrees with the Looney Left on anything. It’s used to make you shut up. It’s used to protect the Looney Left from having to respond to reasonable objections to what they want to do, to make it seem the critics of the Left have no argument to make, when in fact it is the Left that has no argument to make and must avoid reasonable political discourse or have their vacuous bromides exposed as crazy.
So, for example, if you point out an obvious truth, such as including women in combat troops makes those troops less effective, you will be branded as a nut by the delusional ideologues of Leftist dogma. A counter argument will not be made because there isn’t one. Same if you try to point out that raising the minimun wage hurts rather than helps unskilled people at the bottom of the workforce. PC is not meant to encourage congeniality or open discourse, but simply to control what you can say, or even think. It is always used simply to overrule thought and discussion that any Looney Leftist is unable to deal with and therefore finds it offensive.
The simple truth is that PC Leftists are bullies.
Ordinary decent people have had enough of this madness. They’re angry and want it stopped. Donald Trump didn’t cause all the ruckus over PC. He’s the symptom of the disease, not the cause.
