50% + 1 is called democracy. Civil liberties are more liable to be swept away by minorities that come to power. In the US, the republicans often do this because they have minority popular support but a disproportionate representation in government. So the key is to make sure that it's 50% + 1 but also representative of the real population.

The nobility is another example of a minority with disproportionate power. It's important that they are reduced to ensure civil liberties.

All other democracies have safeguards against the tyranny of the majority. Whether it is representativity by state in the US or in the EU, a constitution requiring a large consensus to change in the US, or the senate being elected by the elected officials of small cities in France, it is not true that democracy is just 50% + 1 vote.

What you describe is called a Republic. Pure democracy is precisely 50% + 1 vote.

Worth noting that the distinction between democracy and republic that you're clearly advocating here is a usage particular to Americans. It doesn't have much currency elsewhere.

Countries like the Netherlands, Denmark etc all have safeguards the dilute the power of 50% + 1, and yet they are clearly not republics, being monarchies.

Political scientists tend to talk more of 'liberal democracy' (whether republican or monarchical) v 'electoral autocracy' etc. This depends on the classical use of the term 'liberal' of course, which is another word that Americans tend to use differently from everyone else.

Alexis de Tocqueville would disagree - he believed that intermediate institutions (churches, professions, elites, etc) blunt the power of the state before it reaches average people. A society without intermediate institutions is one where you have an all-powerful state on the one hand, and a largely un-coordinated mass of average people on the other. He thought this was the highway to democratic despotism. (Worth noticing that totalitarian governments focus a lot of their energy on destroying alternative centres of power such as these.)
