might get more representation under some systems but it will usually be such a small percentage that it will make no difference what so ever as to what the gov't does...
This is true for your system. In european democracies the only criticism that can be brought about the system is small parties having a little more power because rarely does one party hold power by itself, usually there is a coalition o a big party + a couple of small ones witch can blackmail a little the big one and the ballance of power usually shifts at least 1 time in between elections depending on the flow.
if anything it will have the effect of making people think that the gov't is more legitimate since minorities are represented....this means that minorities being represented has a tendency to legitimize bad governments....a trap that from how and what you are posting here it seems that you might have fallen into
This is of course true for your presidential system and is the exact opposite
of what is happening in parliamentary/semi-presidential systems.
but if it loses too much popular support it can suffer the same fate as the gov't it replaced.
In Romania the communist party lost support long ago but it took some decades for the people to become angry and hungry enough to make a revolution. It's easier to vote than to become an armed insurgent.
Without people supporting a government will not continue.
Oh yes it will, it can continue quite a long time before been brought down.
the more intelligent the people are the more likely they will make smarter decisions about whose guns they will decide to hold and whose rivals they will decide to shoot
But what do you do when you have just 1 or 2 options on the voting paper ? Start and armed insurgency ? Then go on, I want to see you on tv
All governments are based on coersion
Some more, some less. That was the point of creating democracy in the first place.
I can't believe you are defending totalitarian principles. Please learn a little about the democratic principles. Not all forms of government are the same. Democracy has been proven to be better by history. Also not all democracies are the same. Some are more democratic some less.
