Alright then:
1) This isn't AmericanDebatePolitics, so my opinion is as worthy as yours on the matter. Furthermore, it's basely xenophobic to disregard a foreigner's opinion on how to fix your nation, when it might just be, in fact, that a foreigner's viewpoint will bring the solutions that are readily unapparent in America.
2) I would like you to show me these facts claiming to contradict my less guns = less gun crime theory. Because I've already shown you facts proving my point. The burden of proof is on you to overturn my evidence.
3) Violent crime has increased since the gun ban in the 90's about 4%. The amount of murders there are in a year, EVEN EXCLUDING GUN RELATED MURDERS IN BOTH COUNTRIES, is still an order of magnitude higher in the States than in the UK. Then you get to add on the 11,000 violent gun crimes a year in the States, and you can see how ridiculous your claim was
4) You're wrong, and I'll explain it to you with very, very simply math, so that it just might take root in your head. Fact One: There are 11,000 violent gun crimes in the US per year. Fact Two: There are on average about 70 in the UK per year. Fact Three: Whites make up about 80% of the US population, with blacks making up about 10% of the population. What this means is, you are attributing in excess of 10,930 gun crimes per year to a demographic that is A) Quickly moving into the middle class, and B) 1/8th the population of whites in America. To me, that just sounds like racist, fearmongering bull****e.
5) I'm really not all that clueless about America, as I just proved you wrong on all five of your points, didn't I?
