In the late 1940s Joe McCarthy, an ignorant Senator without conscience, knowingly picked an issue without substance to take him from obscurity to the national stage. The fake issue was communism. He used the non-issue of anti-communism to conduct hearings that ruined innocent people's lives by accusing them of being communists. All the while, few noted that being a communist was not illegal in the United States. And, few noted that McCarthy never found a single communist.
The end result was that McCarthy was shown to be a proven liar. Joseph Welch ended McCarthy's reign of terror with the questions, "Have you no decency, sir? At long last, have you no decency?"
George Bush, another ignorant man without conscience has done the same thing, knowingly grabbing on to another issue without substance, the faked danger of Iraq, to bring him from obscurity to fame and fortune. Bush has been shot down by the many Joseph Welches of today, pointing out that Bush is a proven liar. And, like McCarthy, Bush has never found a single WMD.
Rush Limbaugh, another ignorant, conscienceless man has knowingly picked another issue without substance to bring him from deserved obscurity to the national stage, wealth and notoriety. Limbaugh's issue is hard-right, conservative Republicanism, an issue that has been proven, with devastating effect, entirely false by its prime practitioner, George Bush.
Although Limbaugh will never, ever directly admit that his ideology is flawed, that it has no substance, that it is only a vehicle to make him famous and weallthy, he has indirectly admitted this and confessed that he has no confidence in his beliefs.
He has done this by bring to the attention of his listening public the one devastating flaw in an unsupportable belief. That one flaw that Limbaugh fears is that if there is just one dissent containing truth, reason and logic from his made up, contrived and invented ideology, it is such a danger to his beliefs that he will be exposed as a faker and his whole, fake ideological empire will be destroyed.
This fear of dissent and the need for unanimous agreement is the defining characteristic of unfounded, untrue beliefs and ideologies. Everyone must agree with them or their untruth will be exposed. Those who are confident in their knowledge of the facts and the truth have no fear of being exposed as believing in the false. Their knowledge of the truth will always be supported by the evidence.
That's why Limbaugh must have everyone agree with him, because that is the only support he can get for his unsupportable beliefs. The essence of Limbaugh's quest for unanimity is that those who don't know must have no disagreement with their lack of knowledge, while those who know have no fear of and know that the truth cannot be affected by dissent.
Limbaugh, in his ignorance, doesn't understand that agreement, even unanimous agreement, is not evidence and is not proof of anything that he might choose to believe.
That's why Limbaugh has confessed that his beliefs are unsupportable, by actually admitting that the only support he can get is by having no one disagree with him.
Joe McCarthy died in alcoholic obscurity as a result of Joseph Welch's questions. Joseph Welch's questions to McCarthy are no less appropriate when, at last, they are addressed to Rush Limbaugh. The appropriate result would be the same.
