Political Correctness; A question........

[BlueStreak]

I have a question for the group;

As I recall, when "political correctness" first appeared in the 1980-90s, it was basically seen as an attempt to silence opposition on clearly political issues, by the left. However, it appears to me that somewhere along the line, it has been turned by the right to silence any opposition from the left. Case in point;

In 1992, a person cries "racism". Someone expresses that they don't believe this situation is, in fact, racism. The left responds; "Ooooh, you can't say that!" before any facts are gathered and examined.

Fast forward;

In 2016, a person cries "racism". The right has a fit and shouts down the claim, before any facts are gathered and examined.

Now, who is being "PC"?

Moreover; How do you make the distinction between that which is a matter of political correctness and that which is a simple matter of common decency?

Our world seems to have filled up with idiots who find any objection to their ignorant statements and abhorrent behavior to be "political correctness".

Thoughts anyone?
