Right, and IMHO the Fair Tax proposal qualifies to fill your prescription.
If the critics would be honest about the real cause of their negative opinion being the result of misinformation or incorrect assumptions their bias against it would soften and they would then admit that it's actually a fair and well thought out proposal, and is infinitely preferable to the outrageously intrusive, unfair, cobbled together monstrosity that we're saddled with now.
A system that requires as much time, effort, and expense in order to determine how much tax is owed as the current system requires is more maddening to me and many other Fair Tax advocates than having the money extracted from our pockets. No tax is desirable and no tax collection system is perfect, but I suppose I will never understand why anyone intimately familiar with the current grossly Un-fair Tax would prefer it over the Fair Tax.
As a critic, I think if the proponents would be honest about the real cause of their positive opinion being the result of misinformation or incorrect assumptions then their support would go the way of the do-do bird...
