I'm not convinced the Boston Tea Party is comparable, and not just because things have changed in two hundred years. The tea tax was a specific issue. The Tesla is symbolic. I certainly hate Musk and would not want to buy a Tesla. But targeted property damage of this sort is likely to have a contrary effect, and risks collateral damage that is not acceptable, such as accidentally killing someone or burning more than you intended, and though it might constitute a public gesture, its harm to Musk is essentially nil.
Mind you, I also agree with Stacy that comparing this to the actual terrorism, treason and personal injury of the Capitol riots is stupid, excessive and wrong, and of course that did result in one death, of a terrorist not a heroine. But realizing that something is not as bad does not make it good.
