Then I would suggest that you read our Second Amendment. EVERYONE has the Right to "keep and bear arms" here.
That's just the problem. EVERYONE can buy a gun and shoot your ass if they don't like what you say. I don't think that your second amendment is safe enough for those who have bad intentions. You know you're own history right? (drive-by shootings, shootings at college, washington sniper)
Which is exactly why the Nazi's were able to over-run your country so easily back in '40. Why do you think that NOBODY has made a serious attempt to invade the US since 1812? Because they KNOW that if they do, damned near everyone they see is going to have a gun in their hands, and it's going to be pointed at THEM!
Well, since you know a lot of history, you would have known that Hitler had a lot more people in his country (and other countries) who followed him. Even in Holland there were people who supported Hitler and helped him. So there weren't enough people who could face the army of Hitler.
Besides that, Hitler's mission was to conquer the world in the end.
Well, it's kind of hard to "make love" when somebody comes in, kills you, and RAPES your women, you know, like the Germans did. One would think that you people would have learned from your own history, but it would appear that you need to be reminded.
