I don’t think our case was that these sales don’t happen, it’s that the guns in these sales are almost NEVER used for crimes, particularly mass murders, and thus blocking these sales/transfers will not affect crime, but will make it that much tougher to own/sell/buy guns, which will have the effect of less and less people doing just that.
And THAT is what the Left needs - less gun owners, and when gun owners are few enough, the Left will simply FINISH THE JOB and make private ownership Illegal...and the votes on our side will NOT be there to stop them, or even slow them down.
It is just another step to total disarmament. If they can ban one type of gun because it LOOKS like a military weapon, they can ban them all.
