Gradual erosion of freedoms and rights for the benefit of the "common good" is an insidious thing. It can and will happen to you unless you stay vigilant and are prepared to put skin in the game on a personal level.
Some of our most restrictive legislation was passed into law on the heels of terrible tragedies (Ecole Polytechnique massacre), by self serving anti-gun activists. To the average Joe on the street the new laws sounded pretty reasonable - hell, you licence cars why not guns? Why do you need high capacity semi-auto rifles? Who really needs handguns anyway? etc, etc
Throw into the mix political correctness and a changing demographic due to immigration and it looks like a bleak picture.
Stay awake, get involved.
