1. was being forced down the colonists' throats,In other words, the colonists did not "protect" tea in order to raise revenue or protect jobs. The attempt by current-era protectionists to seize-upon what was essentially an common uprising as an example of enlightened economic policy falls short. To highlight this shortcoming, one must merely ask themselves: what is the current state of our domestic tea industry?
2. the colonists were excessively taxed by the government doing the importing, and that
3. the colonists' response was to outlaw its consumption.
Apart from the matter of falsely "appropriating" the motives of the Founding Fathers in order to support various protectionist claims is the problem of finding justification in the language of the Constitution itself. Sure, Congress has the power to levy tariffs and regulate trade. But the Senate also has the authority to ratify a Treaty reducing tariffs or unregulating trade. Article II, Section 2. Yet another problem with the protectionists' selective interpretation.
Furthermore, if the actions of the Founding Fathers (and the actions of the fledgling Republic) exclusively are to be viewed through the prism of protectionism, how does one explain the Barbary War, which occurred shortly after the Revolution itself? Clearly, the U.S. was protecting its interest in free-trade by force. No free-trader dares therefore to claim that military action is the first step to unrestricted trade. Moreover, the Barbary pirates, it could be argued, were the ones "protecting" their domestic industry (essentially toll-based transport), although I find it unlikely that one or more of the pirates themselves were claiming that they needed to do so in order to protect their high-paying jobs.
So this is the crux of your dilemna. You are attempting to make a rational argument based on an appeal to emotion. Witness the howls of "it's for our national security," or "the Founding Fathers wouldn't approve," every time the free-market adversely affects a special-interest. Witness how many times the national-security argument then is subordinated to other factors.
Finally, I suggest that your best claim is not to the national-security exception to free-trade, but rather the fledgling-industry exception. Adam Smith understood that a newcomer to the market might need protection from its well-established rivals until it gets on-its-feet. The entire United States was a "fledgling-industry" during this period. The problem that Milton Friedman and others have pointed-out, and that current-era protectionists (maybe deliberately) overlook, is that the "until" never comes.
