You have proof of that or are you just pulling it out of you back side, but automobiles are not protected as a right by the 2nd amendment either
I sure do not see car companies fighting most any of the auto laws in this country.
And the 2nd amendment does NOT say ANYTHING about high capacity magazines either.
I guess any gun company who does not wish the repeal of the 1930s laws restricting Machine gun ownership are "anti-gun" your eyes as well?
