... all of the stuff that you mentioned is in a constant state of flux and change. Laws about carrying guns in schools and government buildings are constantly changing.

It all depends on where you are at any particular time. Some jurisdictions go out of their way to minimize and/or eradicate Second Amendment Rights because they can't effin' read. Disregard of the US Constitution is becoming more commonplace in fringe-loony liberal circles with idiots like o'barry and hillary.

You seem to be one of those "know-it-alls", which is an enormously obnoxious trait.
