Gee, it's the same old tired anti-gun nonsense as usual. They never learn, they never quit, and no gun control that they ever manage to get past ever works, let alone is ever enough to satisfy them.
They should just go live in the UK since gun control works so well and it's so much safer with all that gun control.
They are free to leave anytime and I wouldn't be sorry to see them go. If they don't like it here...
