Lets be Blunt about it: Leftists HATE Liberty.
Leftist extremists hate liberty nearly as much as they hate people who refuse to surrender our freedom.
They also cannot abide the truth it almost comes naturally to them to Lie instead of being honest.
Instead of coming out and saying they cannot stand the fact that people can defend from tyrants and criminals, they came up with the Assault Weapon Scam and its cousin the High Capacity fraud to go after that right of the people.
