Good for you!
Where's that facepalm gif?
Yeah there is. It's a complex topic and you likely don't have the capability to understand it, but I'll explain it to you so you might (at least have a friend explain it to you).
In America we have a higher per capita gun ownership rate than just about anywhere else, certainly in the developed world. That increases the number of guns in circulation and with higher numbers in circulation more and more get "diverted" to bad uses. They are stolen, or used by bad people to do bad things because they are so easily available,etc.
As such your hobby, your true love, guns, are a problem for everyone.
Go to a drug store and see how many boxes of Sudafed you can buy. You are a law-abiding good person, but no matter how good you are you can only buy a few boxes at a time (two in most states I think). That's because Sudafed can be "diverted" to making Meth. So they have LIMITS on how much Sudafed you can buy.
Now I know Sudafed isn't a "right", but the same reasoning applies. I wish you lot could understand topics like that but you stopped listening in school when you discovered guns and guns is all you think about now. You can't seem to think more deeply or strategically. I wish you all were a bit smarter.
