If you knew it was an income tax then why did you say this...
@Because Roberts' opinion also holds that even though the "tax" is not the kind of tax permitted in the first article of the Constitution, and even though the "tax" is also not a tax on incomes covered by Amendment XVI, it is a valid tax (of what kind he does not say) and the existing case law already permits it.
It seems that you're the one coming to an eventual discovery, not me.
He does not say it's an income tax directly. He suggests it's an income tax by saying people with a certain income have to pay it if they don't buy Healthcare. But he doesn't ever actually say what kind of tax it is: only that it's "permitted."
Read the dissent.
Neither you, nor Roberts, nor this blog-pimp have any leg to stand on.
