I simply stretched one clause one direction.
It's pretty much the same technique you are using. You totally ignore history and the actions of the Founders to come up with your own interpretation of the Constitution which you then use to declare un-constitutional an activity that even Thomas Jefferson thought was very Constitutional.
Now, for the main thrust, warp and woof of this debate - you stooped to name-calling first. That means you must be a Liberal!
Well perhaps here you have an opportunity to educate me. Kindly cite me the supporting evidence for your assertion that Thomas Jefferson saw the the regulation of educational activity as a legitimate function of the Federal government.
As for ignoring history -- I think the point of not being a liberal is that we don't assume that a power legitimately belongs to the government merely because it has been usurped in the past.
I would agree that history indicates that there is no practical limit to the power of the US Government beyond whatever public polling and the "democratic" process will allow at any given time. But then, I thought the purpose of FR was to work towards restoring constitutional republican government to America. Democratic usurpation of undelegated power -- government by plebiscite -- is not constitutional and I don't think you've done a very good job of proving oterhwise.
