You've nicely, and quite inadvertently, summarized the ups and downs of democracy -- maybe not your intention, but you've done it nevertheless.. We all know that the defect in democracy is that the majority doesn't always want what's best, but the majority always wants what they think is best. So an adjunct to democracy, and what makes it successful, is the loud voices of opposition, which sometimes takes to the street. The two elements together, i.e., majority rule and loud vociferous protest, result in the best form of government, once an adjustment for risk is included. What I man by that is that a benevolent dictatorship is, of course, the best, and certainly the most efficient, form of government, as long as risk doesn't enter into the picture. But risk does enter, so the best we can do is democracy combined with free speech.
For democracy, i.e. majority rule, to work well, it must be combined with free speech. Democracy and Free Speech in combination are not always wonderful, but always great! When a travesty results from majority rule, unfettered speech comes to the rescue, and vice versa.
