Agreed, PhilW! Ignorance is a powerful weapon in the hands of the gun grabbers. In the recent discussion, I know people who have either been uninterested fence sitters, or very casual gun owners, who just felt like "something" had to be done. They rightly felt awful about what happened, and rightly wanted something like that to never happen again. Unfortunately, they were manipulated by MSM(aka the Ministry of Truth, a wholly owned subsidiary of the DNC). They heard about these evil, scary assault rifles that are murdery and evil, and just didn't have the correct information to work from.
I guess, in short, a lot of the fear comes from ignorance coupled with a very powerful and well put together propaganda campaign. On the bright side, most fence sitters, and people who genuinely don't know any better, are fairly easily lead back to the path of what I like to call "notstupid".
