Let's face it. Our justice system is corrupt and sucks. There have been a lot of people who have been prosecuted for stupid mistakes and victimless crimes and now have lost the right to own guns. I would be willing to bet that a lot of these folks are in this situation because of Clinton and Harris. If a revolution starts or even a BLM or Antifa home invasion happens to them they basically have to let them in and suffer the consequences.
Yes there are other things that can be used for weapons, axes, hammers, swords among other things but if you have 20 people charging your home that won't do much good.
What do these people do when someone comes knocking on their door?
Get a fully automatic .22 pellet pistol & rifle. unfortunately the only half assed solution feasible as of rn. they are toys technically and can be traveled with/carried anywhere.
