This debate seems like a manifestation of a problem with governments: They think they can legislate anything they want. Need access to some communications - green light for massive data collection. Some of it is encrypted - just mandate a back door. School shooting - new gun laws. Any problem activity - we'll just make it illegal. Something not getting done - we'll just mandate someone take care of it. They really do…
A gun ban is a reasonable and effective way of reducing the number of school shootings, as any European on here will confirm. Not sure why you brought guns into this argument other than it being a pet issue.
Remember what happened when the Federal government tried to get some farmer to pay for the grazing land he was using? People several states away showed up with rifles, and they had no skin in the matter. If you tried to take their rifles, they (and many others) would try their best to kill you.
If America were full of Europeans, perhaps it would work. It isn't, so any notion of gun banning in the US is nothing more than wishful thinking at best.
