WOW! That is a pretty dark response. There has definitely been an increase of acceptance of using violence in the name of the progressive agenda.
I, personally, think the Republicans have gone too far already. I was having a conversation a few weeks ago with a gun control advocate about background checks being an infringement of the right to privacy and presumption of innocence. I agreed with him that they make things slightly more difficult on the "bad guys" trying to buy a gun, but they also make it difficult on those of us that have never committed a crime. It isn't fair that we're required to request permission from, and prove our innocence to, our government in order to purchase an item.
More innocent people are affected by these checks than criminals. The NICS is so ineffective that the gun control advocates don't even know it's there. In my opinion, background checks are a sacrifice of freedom for the illusion of safety.
