The gun-banners seek to ban all guns. Banning "assault weapons", a fabricated term, is just a stepping stone.
I've asked several anti-gun LWers if Obama's 2013 Gun Ban had passed, would they be satisfied that it was enough. All avoided the question because the answer is obvious; it's a first step to a total gun ban.
The logic goes like this: If limiting magazines to 10-rounds, wouldn't limiting them to 5-rounds be better? If banning some semi-automatic rifles is good, isn't banning all of them better? They'll keep pushing until all that is left are single-shot muskets and then they'll try to ban those. Only for the poor and middle class, of course, since the rich will always be able to pay for it like abortion.
Gun banners on JPP have already supported a total ban on all guns or all semi-automatic guns.
I don't trust liars and this is the #1 reason why I don't trust Democrats nor will I ever vote for one.
