Not really. But I could answer those and you can again say, well I can easily answer you a second time yet I wont. Here is something else! I'll do a few though, since I know Jefferson moreso than the others.
"A democracy is nothing more than mob rule, where 51% of the people may take away the rights of the other 49%."
Thomas Jefferson
While he is credited for saying this, I'm not sure he actually did.
But here are some other things from him that have citations. If he did say it, then he is contradicting a library of his own quotes on majority rule.
"I subscribe to the principle, that the will of the majority honestly expressed should give law." --Thomas Jefferson: The Anas, 1793. ME 1:332
"All... being equally free, no one has a right to say what shall be law for the others. Our way is to put these questions to the vote, and to consider that as law for which the majority votes." --Thomas Jefferson: Address to the Cherokee Nation, 1809. ME 16:456
"All, too, will bear in mind this sacred principle, that though the will of the majority is in all cases to prevail, that will to be rightful must be reasonable; that the minority possesses their equal rights, which equal law must protect, and to violate would be oppression." Thomas Jefferson, Inaugural Address
"This... [is] a country where the will of the majority is the law, and ought to be the law." --Thomas Jefferson: Answers to de Meusnier Questions, 1786. ME 17:85
"The fundamental principle of [a common government of associated States] is that the will of the majority is to prevail." --Thomas Jefferson to William Eustis, 1809.
"The voice of the majority decides. For the lex majoris partis is the law of all councils, elections, etc., where not otherwise expressly provided." --Thomas Jefferson: Parliamentary Manual, 1800. ME 2:420
"Democracy is two wolves and a lamb voting on what to have for lunch. Liberty is a well-armed lamb contesting the vote!"
Benjamin Franklin
"Against such a majority we cannot effect [the gathering them into the fold of truth] by force. Reason and persuasion are the only practicable instruments." --Thomas Jefferson: Notes on Virginia Q.XVII, 1782. ME 2:223
Back in the day of our founders, mentions of democracy meant direct democracy, and they are rightly not too keen on that. But they are largely for both representative democracy and majority rule.
That invalidates nearly all of the rest of your quotes.
I'm not saying that a representative democracy is perfect or everlasting. Nothing is, which makes those particular quotes useless. In fact, it probably
is all those bad things from your quotes, despite that they are nearly uniformly talking about direct democracy. And it still is the best thing we've got.
Feel free to continue running away from the issue of the vote and majority rule.

You are correct that this discussion is useless, since you have used the words objective and self-evident, which are at the core garbage.
