I’ve seen the term militant democracy used to describe how democracies will have laws that curtail political expression and representation when it threatens the survival of liberal democracy. Another articulation is that the marketplace of ideas is not enough to keep anti-democratic players out of a critical mass of power (not necessarily a representative majority, just enough to erode democratic norms/guardrails), thus the society has made the tradeoff of empowering some subjective but hopefully impartial institutions of government to gatekeep the political arena from the most dangerous actors to democracy.
