I’ve been looking into getting a heat pump in the northern US and for heating it doesn’t seem to be worth it quite yet. The problem where I’m at is that it gets very cold and natural gas is pretty cheap but electricity is expensive. I hope this changes soon. It would be a no brainer if I were replacing a resistive heater though.

I know dignity when I see it!

I’m not interested in discussing the first paragraph but for the second; as I understand it you have to define something before you can regulate it. The pedantry is over the definition of a machine gun in that a bump stock doesn’t really apply because each bump is a separate action by the operator, and the court apparently agreed. The definition of a machine gun can be changed perhaps to define a maximum rate of fire instead of number of rounds fired per trigger pull or something.

FWIW you can bump fire without a bump stock, It just requires a little bit of manual dexterity
