The Argument from  Intimidation is a confession of 
intellectual impotence.
'...the Argument from Intimidation does not consist of introducing moral judgment into intellectual issues, but of substituting moral judgment for intellectual argument...  But a moral judgment must always follow, not precede (or supersede), the reasons on which it is based."
Ayn Rand on The Argument from Intimidation,”There is a certain type of argument which, in fact, is not an argument, but a means of forestalling debate and extorting an opponent’s agreement with one’s undiscussed notions.
It is a method of bypassing logic by means of psychological pressure . . .
It consists of threatening to impeach an opponent’s character by means of his/her argument, thus impeaching the argument without debate.
Example: “Only the immoral can fail to see that Candidate X’s argument is false.” . . .The falsehood of his/her argument is asserted arbitrarily and offered as proof of his/her immorality.
In  today’s epistemological jungle, that method is used more  frequently than any other type of irrational argument.  It should be  classified as a logical fallacy and may be designated as “The Argument  from Intimidation.”
The essential characteristic of the  Argument from Intimidation is its appeal to moral self-doubt and its  reliance on the fear, guilt or ignorance of the victim.
It  is used in the form of an ultimatum demanding that the victim renounce a  given idea without discussion, under threat of being considered morally  unworthy. 
The pattern is always: “Only those who are evil (dishonest, heartless, insensitive, ignorant, etc.) can hold such an idea.”
The  Argument from Intimidation dominates today’s discussions in two forms. 
In public speeches and print, it flourishes in the form of long,  involved, elaborate structures of unintelligible verbiage, which convey  nothing clearly except a moral threat. 
“Only the primitive-minded can fail to realize that clarity is oversimplification.”
But in private,  day-by-day experience, it comes up wordlessly, between the lines, in the  form of inarticulate sounds conveying unstated implications.  It  relies, not on what is said, but on how it is said—not on content, but on tone of voice.
The  tone is usually one of scornful or belligerent incredulity. 
“Surely you are not an advocate of capitalism, are you?”
And if this does not  intimidate the prospective victim—who answers, properly: 
“I am,”
the  ensuing dialogue goes something like this: 
“Oh, you couldn’t be! Not really!”“Really.”“But everybody knows that capitalism is outdated!”“I don’t.”“Oh, come now!”“Since I don’t know it, will you please tell me the reasons for thinking that capitalism is outdated?”“Oh, don’t be ridiculous!”“Will you tell me the reasons?”“Well, really, if you don’t know, I couldn’t possibly tell you!”
Let me emphasize that the Argument from Intimidation does not consist of introducing moral judgment into intellectual issues, but of substituting moral judgment for intellectual argument.
Moral evaluations are implicit in most intellectual issues; it is not merely permissible, but mandatory  to pass moral judgment when and where appropriate; to suppress such  judgment is an act of moral cowardice.  But a moral judgment must always  follow, not precede (or supersede), the reasons on which it is based.
The unfounded argument is accompanied by raised eyebrows, wide-eyed stares, shrugs,  grunts, snickers and the entire arsenal of nonverbal signals  communicating ominous innuendoes and emotional vibrations of a single  kind: disapproval.
If those vibrations fail, if such  debaters are challenged, one finds that they have no arguments, no  evidence, no proof, no reasons, no ground to stand on—that their noisy  aggressiveness serves to hide a vacuum. 
the Argument from  Intimidation is a confession of intellectual impotence.
