ARE EITHER FOUNDED on false premises or jump too soon to the wrong conclusions.
For example: “I disagree with what you say, but will defend to the death your right to say it.”
This lends too much credibility to mistaken notions and patent nostrums. After all, anyone with the courage of his convictions, and the wit to learn the truth of most contentions, will be able to state categorically (and be correct) that the Left is almost always wrong on the merits.
So the above shibboleth doesn’t go far enough. Not only must the speaker In the Right defend to the death his opponent’s right to speak, but he must defend his own right to mock unmercifully, and without physical consequences, the false premises, faulty logic, and mistaken conclusions of the typical leftist’s “reasoning” on any given subject.
