I get the sentiment but if things go as bad as I think they are going to go, firearms are just going to make someone's situation devolve even faster. Unless we go full apocalypse and the government completely collapses, if you get into a situation where firearms are required, you're just going to move to the top of the list of issues the government needs to take care of.
Safely owning and knowing how to operate a firearm isn't to defend yourself against a platoon of the US Army with armored units. If it comes down to that then it's too late.
It's being able to defend yourself, your family, and your community against a militia acting under color of law.
The question is whether you believe that US fascists are going to embolden private militias to go out hunting.
If you don't think that it's possible, continue not safely owning and knowing how to operate a firearm. Everything is going to be just fine, nothing to worry about. Midterms are in two years, watch some TV. This is fine.
If you think it is possible, then your options are being a nice polite liberal who just puts up their hands before being murdered, or putting up a fight if need be.
The strawman here is that non-fascists owning a firearm are only doing so to take on the US military and a tanks rolling down your street.
The actual argument is that there's usually a lot of time, often years, where individuals could have defended themselves but "chose" not to.
