I think the problem here is that your inference that a flat tax rate would be good because the total amount of income taxes collected each year as a percent of total income hasn't change has had no supporting evidence presented, and it's such a leap to most people that they don't even understand that's the argument you're making.

Exactly why do you believe that since the total percentage of income collected hasn't really changed that means a flat tax is a good idea? The reason for a progressive tax is not to raise the total amount of taxes collected, but to change which people it is collected from proportionally. I'm not sure what the total percentage collected has to do with that.
