Actually a republic represents neither democracy nor the lack thereof.
The U.S., Germany, France, Italy, Israel all being republics and democracies
China, North-Korea, The U.S.S.R. (when it still existed), also republics are/were not democracies.
Of course, it shows how some people are now refuting the idea they live in a democracy, simply because... Democracy could also end their ideas when the majority votes otherwise, so suddenly democracy doesn't suit them. I heard other opinions about democracy from them when the majority was more in line with them.... how convenient...
