Yserbius,
“I don’t think it’s impossible, just very difficult and it would take a long time”
It would require so much legislation that would be met with so much resistance. While all that legislation is being worked out, the manufacture and sale of firearms would go through the roof, just exacerbating the problem. Then let’s say they actually do manage to put bans in place, imagine the logistical nightmare of getting people to give up hundreds of millions of guns. Imagine how many people won’t go down without a fight. The country will tear itself apart.
Of course all this is assuming you can repeal the second amendment, because otherwise none of this even gets off the ground.
It’s virtually impossible, and it would take forever. Keep fighting for it if it makes you feel better, but it’s a bad idea and it will never happen.
