Democracy sucks because in the end, you're forced to do what the majority says or else you will be killed.
It's NOT Democracy that goes around that "abide or be killed/arrested", it's the Government, they're different things.
You got the very same "abide or else..." action within almost all other forms of State, Dictatorships use it even more lightly.
Democracy is just the way issues are addressed and bodies are elected not how to deal with those who don't comply.
BTW, this so called "reputation" systems remembers me why many people complaint of BS on Democracy, it's not "just" politicians fault, it's the people's fault as well, people love to be BS'ed. Like if I come here, just say what you guys want to hear, regardless I would do it or even think on such way, and see my "rep." rocketing... a bit like the votes in a regular democracy.
