Like Daniel said earlier today, we're almost like a third world nation in terms of attempted coups, revolutions and seccesionists (not like that's a bad thing, it just makes things more interesting.)
The main thing is that all you need to stage a "coup" is to post a topic stating that that's what you're doing. It's considerably easier and with considerably less risk and effort than coups in real life.
A counter-argument against taking these into account could be made that it's impossible to force anything on anyone. The only reason that these "coups" are taken into consideration at all are because people pay attention to them and react as they would in real life. If the coups were just ignored, it would be as if they never existed.
In addition our elections are far from squeaky clean, what's the last one we had that didn't have major controversy or accusations of fraud?
I would say that they're no worse than American elections.
Governments and parties also tend to be unstable, parties rarely last long and resignations and effective nullification of election results do happen on a fair basis
Besides the "effective nullification of election results" bit (I'm not sure what you mean by that), I can't disagree with much there.
Still I'd say 3 for Political Liberties and 2 for Civil Liberties at the moment. The CL score would've probably dropped before, such as during the West Atlasia and Southeast crises.
Uh, why would civil liberties be anything greater than 1? It's impossible to coerce anyone into doing anything that they don't want to do. It seems to me that that's as much freedom as anyone could hope for.
