I have gone backwards and forwards on this. I would say I am still on the fence. I'm not American so my opinion isn't really valid.
A couple of things:
People don't understand that it's just not a matter of banning a gun as an item. I think for a lot of American citizens they view the gun as a symbolic representation of their freedom.
Instead of just opposing guns, why don't people come up with a viable solution. Anyone can march and say 'no more guns' but just like protesting climate change, why don't you come up with a viable solution?
I actually don't think that there is much opposition from gun enthusiasts to make some legal changes around ARs, I think if the focus is on a certain type of gun there can be some consensus.
