That’s still the purpose of the second amendment, for people to own guns to defend themselves and others against tyranny

No it isn’t and it never was. Go read it. It’s about defending the state from invaders. Wars at the time we’re mostly fought with militias, especially for more poor or smaller nations, like the new United States at the time. We didn’t have a standing professional military for a whole so our military was solely militias, and as such they should be legal and trained, hence the 2nd amendment.

I largely support (safe and with training) gun rights. They’re protected by the 9th amendment, whether the 2nd does or not. It’s just this blatantly incorrect repetition that the 2nd amendment is about something that isn’t written in it is crazy. It’s really short and pretty clear. I feel like no one supporting this idea has actually ever read it, or at least hasn’t considered what it actually says.
