A lot of progressives and radicals in the US are making the mistake now of downplaying the utility of owning a firearm, many of which are saying it's better to learn first aid.
"I've never used a gun to take or protect a life, but I have used first aid."
Learn first aid, by all means please. Don't get a firearm (or knife or pepper spray or baton) if you can't learn to use it or doing so would be too risky to you. But looking at the past 20+ years of society and thinking those rules will apply under a rabid fascist regime if pure folly.
First aid can only be rendered if someone is there to drive the attackers away. If fascists jump you or start shooting at you, knowing how to bandage a grievous wound means very little if said fascists are still actively attacking.
"Not everyone needs to learn self-defense. That's what *community* self-defense means."
Not everyone can, but everyone who *is able* should learn the means of defending themselves and others. *You* are part of the community, and you too need to defend it. Deferring it to some nebulous third party (even if it's "antifa") is how you get warlords or are left with no one to protect you.
You (yes you personally) have some responsibility to learn to take care of yourself, be it disaster prep or self-defense, because if you aren't prepared, you become a burden on those who are. You become a drain on critical and limited resources. Yes, mutual aid exists, but we can stretch that much further and take better care of those who can't fully care for themselves if everyone who is able first takes care of themselves.
Don't get caught in a dangerous situation. Don't do so unarmed. Don't get injured. You have to learn all these skills. If you don't, it's okay. People will still be there for you. But please try.
