I think it doesn't matter your feelings about any poster's debating style. That aside, there is no such animal as a flat income tax that eliminates withholding payroll taxes; nor is there any flat income tax proposal that eliminates withholding. Perhaps that is something that needed outlining for you?
Or are you simply arguing nonsense?
"there is no such animal as a flat income tax that eliminates withholding payroll taxes"
What are you talking about? Do you mean besides Steve Forbes and Dick Armey?
