I've said it before on this board and I'll say it again; the right wing answer of "any laws on guns are infringement" is going to be what causes a total ban in this country.
Mass killings can happen anywhere and with anything, like that bow attack in Norway shows.
But the severity and commonality of mass deaths by shootings are a purely American problem.
The younger generations aren't stupid. They can look at every other country that has tighter restrictions and see how fucked up we are. They can see that the GOP response of "we need to fix mental health" doesn't hold water for a party that consistently votes against access to that health care. They can see that the idea of "give teachers guns" doesn't make sense in an already stressful and underpaid profession.
I'm not saying that the DNC is right to try and reenact a ban (they aren't), but I am saying that there is only one party that actually seems to be trying to fix the issue. That's a problem.
If you don't try to fix the issue and maintain the right to bear arms, you'll lose that right.
For all the people bitching about "liberals trying to disarm us", you're going to bring it upon yourself in some weird self-fulfilling prophecy.
