If it came down to a choice, which would you rather, a ban on violence in movies/games or a ban on what the other side refers to as assault weapons and high cap magazines? Those may be the choices before it's all said and done. When the powers that be are discussing violence in the media they're not discussing assault weapons. It might come down to giving ground on either the 1st amendment or the 2nd amendment.
Every right is the most important, which is to say every right is equal... There is no one above any other.
