My cultural background has a major influence on my way of thinking, especially concerning "Gun Control", which I consider "People Control", and, for the most, part, I'm against governemental sanctions limiting my access to this freedom. I'd like to think that a lot of us here would agree... to a point.
With no flames intended and not being European, but trying desperately to remember things learned from the past... by naming one particular group, be they African Slaves brought to America, Jews, Muslims or Native American Indians, American Japanese, etc. some of whom might, or might not, be responsible for acts against (to coin a phrase) the "greater communities well being" (whatever that means), are you not setting up conditions for yet another "People Control" movement if these persons cannot be armed?
Granted, today in the news, religion might be THE if not A major factor, but, so might race, unemployment, envy of others who have more, education or lack thereof or just "their" cultural background. Or they could just be "in the way" of progress or a drag on the local economy.
As an exercise (in futility?) consider this thread re: EU "Gun Control" looking at it (G.C.) as "People Control by the State", knowing that there is not a darned thing you or I can do to change their day to day, knowing that while some of those who have discussed this appear to be highly intelligent, their "norm", their cultural background is not bothered in the least when their "State" mandates and implements yet another measure of "Control".
Or is it?
Objects, like Guns? Guns have no feelings, no emotions. They cannot vote. Their Control is good, indeed, needed. This is the argument of some.
Control of Certain People? Hopefully, every man, everywhere, is made a little uneasy when the "State" requires control of "Certain People". Here in the US, we all know that Madison, et al, were forced to include a limitation to the newly written rules our gov't was to follow. We still ended up with Slavery and the Native American problems, the resolution of which, we CANNOT forget.
This time, maybe it's not Gun Owners. Maybe it's (yet again) a small group of Angry Young Idealists from another cultural background.
Hard to pick them out of a crowd.
So let's punish everyone in that group for the acts of a few?
Maybe. Maybe Not. Been There. Done That. It can sucketh... largely.
