(however defined at the time, its parameters change)
Becomes more important than free discourse
(ie. you are no longer allowed to hold an opinion that differs from the narrowly defined orthodoxy)

Is a vital check against tyranny
And the kind of groupthink
That leads to awful things being done
To those on the wrong side of history.
