Thanks in part to Mike, this forum has been fairly free from some of the worst.
It is obvious that people have adopted "zombie" as a euphemism for bad person because we don't promote the idea of killing people, even though we need to recognize that defense of ourselves against the actions of another may force us to that.
But we don't need to emphasize it. One small thing we can do is to stop calling all firearms "weapons". I realize this is due to some folks wanting to play soldier (some of whom could not get through the first day of basic training), but most of our firearms are not "weapons." Even if a firearm carried for self defense might be a "weapon", most sporting arms are neither intended nor used for that purpose. An antique, like a Civil War rifle-musket, may have once been a "weapon", but that term is hardly suitable today.
