Can someone explain rationally why we should not have an assault weapons ban?
Several reasons actually, which I'll outline below. First, let's define our terms. As commonly defined nowadays, an assault weapon is a semi-automatic rifle, chambered in an intermediate caliber (almost always .223), and designed to cosmetically look like (and sometimes possess features of, such as flash suppressors) military weapons like the AR-15. Now, onto the reasons:
1. Focusing on the weapons platform is stupid. Would you feel better with an assault weapon ban in place and forcing a shooter to use something even more dangerous instead, like a Mini-14 or sawed-off shotgun at close ranges or a high-powered main battle rifle at long ranges?
2. None of the commonly defined traits of an assault weapon make it any more dangerous than any other firearm. The presence or absence of a bayonet lug on weapons isn't going to make the next shooting any more or less deadly.
3. Fixating on high-capacity magazine availability for assault weapons is stupid. If they were really
that dangerous, you should move to ban them for police also. Probably even more so for police, with all the stories I hear about suspicious homeless person with no weapon being shot 86 times by police. In any event, blanket bans on all high-cap mags is especially stupid, since limiting the size of magazines in my .22LR pistol I use for plinking at the range in no way makes you safer.
