Politically correct speech and thought provide us with the predigested morality of self-appointed ideologues, the profane consensus of mediocre minds, in lieu of our own common sense and the collective wisdom of the ages.
Wm. B. Fankboner
In a nutshell. In other words, you (impersonal) may have your own moral standards and I have to respect that, but do not presume to impose them on others. You have neither the intellectual nor moral standing to do so.
