All of this is true. Yet many firearms enthusiasts are still disgruntled by the current situation because they interpret the intent of the 2nd Amendment as arming the people at or near parity with the government, as a bulwark against tyranny. And the current state of regulations very much prevents the "at or near parity" part there, very few (0?) American civilians have legal armor piercing ammunition, anti aircraft weapons, anti tank weapons etc. Meanwhile every podunk city has a militarized police with hardware that would be the envy of many 3rd world dictators, to say nothing of the Feds/various 3-letter agencies/secret police etc.
