I fail to see how banning guns makes people freer.
IIRC, nobody made such claim.
That's the entire purpose of having a republic.
The purpose of a republic is that you don't have a monarch. Which isn't what these polls were about either...
Oh, so Germany was still a republic under Hitler? Was France a republic under Bonaparte?
It's a knee-jerk reaction to restrict liberty. Norway isn't exactly Switzerland, either. The direction of such a law wouldn't even make any sense.
The United States restricted liberty with the Patriot Act. A lot of good that did us.
These types of laws only serve to hurt liberty. Loss of liberty leads to the loss of free government (republic, despite your lazy terminology, means 'rule of law'). This means tyranny, where liberty is substantially even less.
