Yep, bogeyman arguments as ever. Lots of countries have presidents, you don't hear scare stories as they get voted in then get on with their job.Civilised? Like the US you mean?
Where currently, one of their ex-presidents is on trail having been accused of rape and tried his best to reverse the legitimate election result? Or do you mean those presidents that murder the opposition and stay in power for decades, regardless?
Judging our potential options based on a nutjob former colony where a gun is a necessity isn't very relevant.
