It is a mere assertion that the vast bulk of the Us would rise up in rebellion if such a ban were proposed. I don't believe it. Why not try it?

On the other side of the story, it remains the case that all it needs for evil to triumph is for the peacable folk of the US to do nothing. And while you do, your children will continue to die at a far greater rate than here in the UK, and the parents will weep, but only have themselves to thank for their inaction. And we will continue to call your country as a whole barbaric, uncivilised and unfitted to lead the rest of the world, because you have barbaric and uncivilised laws applicable to all.
