You're describing Karl Popper's "paradox of tolerance": https://en.wikipedia.org/wiki/Paradox_of_tolerance https://en.wikipedia.org/wiki/Paradox_of_tolerance > I do not imply, for instance, that we should always suppress the utterance of intolerant philosophies; as long as we can counter them by rational argument and keep them in check by public opinion, suppression would certainly be unwise. But we should claim the right to suppress them if necessary even by force; for it may easily turn out that they are not prepared to meet us on the level of rational argument, but begin by denouncing all argument; they may forbid their followers to listen to rational argument, because it is deceptive, and teach them to answer arguments by the use of their fists or pistols. We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant. For me, the clearest way out of the paradox of tolerance is the dictum that "the Constitution is not a suicide pact" (see https://en.wikipedia.org/wiki/The_Constitution_is_not_a_suicide_pact https://en.wikipedia.org/wiki/The_Constitution_is_not_a_suic...). The price of admission to the sphere of tolerance established by the Constitution is (or ought to be, anyway) the willingness to extend the same tolerance to others. If your goal is to overthrow the Constitutional order and replace it with a dictatorship, a theocracy, an ethno-state, etc. etc. etc., you forfeit the right to shield yourself behind the document you're trying to tear up.
