The Right cannot see both sides of any issue. They cannot (or dare not) treat any rival viewpoints with respect, not even the respect needed to address or refute them. This alleviates the Right from the burden of actually meeting a burden of proof, indeed, of actually making any argument at all. They just ask opposing viewpoints to shut up.
The great selling point of the Right, the great promise of Mac, is that all issues are Solidox and settled and the great debate of the human condition, all the mysteries of life, are no longer open to discussion. The matter is closed. Talk must stop. Correct thinking is true, incorrect thinking is heresy. You must shut up. You must shut up. You must shut up.
