The idea that no-one should have an opinion about what goes on in another country is ludicrous. We all do that all the time including Americans. Likewise the idea that it is people knocking Americans and is a case of us and them is also ludicrous. I don't know that many Americans but the ones I do know well are very anti guns and despair at the continuing gun culture. In fact there may now be a majority against stricter gun control laws (ie the url below 50% are against and 47% for stricter laws) but it is still a divide where almost half say there should be stricter laws. So it isn't an American v the rest situation when it comes to how people think. Though saying that I imagine for the vast bulk of Brits the idea that the way to protect society is to flood it with even more guns, which some seem to be advocating, looks nothing less than crazy!
