I do not think this is an argument you want to make. Following this logic to it's ultimate conclusion is that we should just ban black people in the United States from owning guns, and I suspect neither you nor I want to do something so racist.
"Anglo" culture can support it just fine. The U.K. actually had lower violent crime rates before they banned guns. The fact that they felt the need to ban knives in London has very little to do with "Anglo" behavior.
Likewise, most places in the U.S.have rates of gun violence comparable to Belgium or Switzerland.
