The truth is, Progressives don’t care about weapons in the hands of criminals. In fact, they rather like them since they allow Progressives to keep trying to ban all firearms.
Progressives don’t like weapons in the hands of law abiding citizens. Why? Because those weapons are likely to be used on Progressives if they get too obnoxious.
If somebody wants to take your firearms away it is probably because they are about to do something to you that you will object to - violently. Like confiscate the contents of your 401K for instance.
Your health care, your guns, your 401k, your right to post on the internet anonymously, your right to drive your car without GPS tracking mileage (only for purposes of taxation?), the right to buy and sell using cash, your right to educate your children as you please, your right to buy/sell gold/silver without informing government (background check for gold coins), your right to decline to approve of same sex marriage, your right to life, liberty and the pursuit of happiness.
At some point, we must obey the fundamental principles expressed in the Declaration of Independence:
“...But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.—Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government...”
Happily the closer we get to this point, the more easily it will be for people to see that the present government is more dangerous to liberty and prosperity than what a Constitutional Convention might produce and that would pass ratification of the surviving States.
