it's very rare for someone to need an assault rifle for self defense. we're talking maybe hundred per year of examples, i'd think. but how often are those guns used in mass shootings and for murder? much more likely.
assault rifles are not just like other guns in scary lookin form. they are more efficient at shooting multiple people quicker. that's because of their spread and their ease of triggering.
yes knives kill more people than assault rifles, but when you consider how many murders are done by the rifles versus the knives, the rifles have a higher rate of murder.
gun are not just tools. people are more likely to kill if they have a gun. this is common sense and backed by science. (gun murders are wildly out of control in the usa versus other countries while non-gun murders are not- this isn't just a bad person problem. areas with more guns have more murder)\

people dont kill people, bullets do. ('guns dont kill people, people do')
there's no evidence the framers were even trying to protect self defense and hunting, let alone that they were trying to protect mass killing machines
just thought i'd address some of the more common nonsensical arguments upfront.
