Well then take a course in logical reasoning, you are not allowed to appeal to standards that you set for yourself when trying to argue a logical point.
Can you give me some examples of democracies that fell for this reason?
The Athenians did themselves in, they became so weak by voting for pieces of the public pie that eventually they no longer had the means to defend their nation and were easily conquered militarily.
"A democracy is always temporary in nature; it simply cannot exist as a permanent form of government. A democracy will continue to exist up until the time that voters discover that they can vote themselves generous gifts from the public treasury. From that moment on, the majority always votes for the candidates who promise the most benefits from the public treasury, with the result that every democracy will finally collapse due to loose fiscal policy."
Alexander Fraser Tytler, Scottish lawyer and writer, 1770
