I never said a regressive tax is unfair. Regressive gets its name as the opposite of progressive. Progressive was originally meant as an apt description of tax rates that went progressively higher with income. It has in it no hint of fairness, nor regressive a hint of unfairness.
That is until the libs hijacked the word, making it synonymous with their politically "progressive" agenda. I hate how libs get to control the terms used in political discussions, it makes good sound bad and bad sound good. They even have two conservatives here misunderstanding each other.
"Regressive" and "Progressive" are frequently misunderstood terms around here. I once had someone try to explain to me that paying a toll to use a road is "regressive." A real head-scratcher.
