Yes, indeed. But when such a law has been on the books in many/most states’ in similar fashion, and which laws indeed are used to ( probably not often enough) charge and convict those who promote disorder and crime (Antifa, BLM, KKK, left, right anarch, et all, listening?).
To interpolate that lawful firearms training or self defense or even small unit tactics aka US Army/Marine corps Infantry Individual, Squad or Platoon drills are automatically being made unlawful is disingenuous and makes us look like them.
Ranges will open, dads will teach children, moms will get CCWLs, lawful assemblies of armed folks can do stuff. Prices of arms/ammo will not drop due to a glut in the market....
JUST DONT knowingly and intentionally train shooting skills to known felons or leftists, (but I repeat myself....) with the intent to cause civil disorder....
As I spend the evening cleaning stuff....
The problem with your fantasy interpretation is that making such things illegal is PRECISELY WHAT THEY INTEND TO ACCOMPLISH.
