The US government has a terrible track record in defining felony, and has consistently infringed on numerous rights through enforcing bad laws and performing poor paperwork. More importantly though, no right should be subject to government permission. Not speech, not marriage, and not gun ownership.

Many firearm models and features are illegal right now, and people are "felons" if caught in certain areas with the "wrong" magazine or stock. Trump's administration arbitrarily declared bump stocks "illegal," and demanded that people destroy or surrender their property without compensation. That is confiscation and infringement. It is more than just political rhetoric.

My liberty isn't up to your consent. Neither is anyone else's. If your neighbor is dangerous, deal with your specific neighbor, don't demand more power for corrupt government officials over others. You say we need "reasonable limits," but who decides what is reasonable? Not the people who claim a territorial monopoly in violence, that's for sure.
