With democracy, the entire purpose of the system is to enact the will of the majority (at least the majority of the voters), so it does not matter what exactly that will entails in a given case; no matter the idea at hand or the intended or actual outcome, as long as 51% of the populace agrees on appointing a figure to office or implementing any policy, acting as the majority desires is never a misuse of democracy, but a basic manifestation of democracy. And since ultimate truth, including truths about morality and laws, does not depend whatsoever on anyone's consent or preference or agreement with any amount of other people, democracy is inherently antithetical to the necessary truths of rationalism and justice (if good and evil do exist).
Beyond its philosophical underpinnings being entirely contrary to reason, democracy also offers no genuine protection from the majority. Whatever the majority wants is imposed, or else there is no true democracy in place. Either one can deny the majority their wish, which is intrinsically anti-democratic, or one can give into it, no matter how erroneous it is. Of course, since truth itself (starting with logical axioms) is not dependent on belief, consensus, or comfort, no one could support democracy without irrationalistic rejection of the very core nature of reality. There is no such thing as some arbitrary degree of political democracy being valid and another degree being invalid; all democracy is erroneous for the same fundamental reason.
And what of the politician(s) installed by the will of the people? If a tyrant like Donald Trump takes power through democratic means, the only way to remove them from power that is consistent with the tenets of formal democracy, with its recurring elections, is to vote them out—either at the next election in which the general population participates or in some election by representatives chosen by the people. Obviously, this does nothing to truly stop irrational or depraved leaders immediately if there is a rigid voting schedule, and it does certainly does not honor reason, although liberals might hold to it anyway because they wrongly think that the only alternative to democracy is authoritarianism, which is also irrationalistic since logic and morality are the only valid authorities [1] and not any human desire or leader.
Not even the most staunch liberal proponent of democracy would likely think the current actions and professed philosophical ideas of Trump and his underlings are not logically or morally legitimate. Thus, they would probably think that not all results of democracy are valid, even if they are idiotically only reacting to concrete examples in their lifetimes rather than objective logical facts which transcends all examples. Yet, they foolishly continue their allegiance to democracy.
Something that either inherently or haphazardly produces evil cannot be amoral or good even if the overwhelming majority of a population craves a certain course of action. Then, again, entirely aside from any possible moral dimension, democracy is irrationalistic because truth is not grounded in or revealed by any sort of agreement, save for the fact that people agree about a particular issue in a given case. Anyone who participates in democracy, however, is morally culpable for any evil committed by the person they helped put in office, especially if they voted for a certain idea to be championed or for a law to be passed despite that idea or law being illogical and/or unjust.
Instead of looking to reason's necessary truths and then recognizing that some political philosophies cannot be correct, including democracy and authoritarianism alike, liberals still prefer some semblance of democracy and fail to grasp its objective errors. Democracy at least partially gave us Donald Trump's presidency and the catastrophic chaos brought about by the egoism, hypocrisy, and classism (all rooted in irrationalism) of Trump and his Republican party. But foundational truth is not determined by mere consequences either, as democracy is inherently false as a philosophy, however stubbornly liberals admire or praise it and however much a democratically-appointed leader benefits a country. Democracy is good and right, liberals would believe, but the things democracy brings about by virtue of being democracy are (in this instance, at least) asinine and wicked. The former cannot be true if the latter is!
[1]. But God would only be authoritative for logically necessary reasons, and something like the Bible, a text and not a necessary truth or a conscious entity, could only be authoritative to the extent that it is at least consistent with reason and morality, like a human political leader. The authority of such things as the Bible and a politician is still derived from something that is authoritative and is surrendered proportionately at any deviation from logic and morality.
