Rifles are not dangerous and will never be banned.
Why not? It isn't for you to decide what I do and don't need. I could ask why anyone would need an education. After all, you opted out of one. Why does anyone need the Internet?
You would do well to learn about firearms if you're going to attempt to preach against them. Do you want to know how many people were murdered by automatic rifles in the US last year? Zero. Not a single soul was murdered by automatic rifles. Automatic rifles are not sold at gun shows, they are not traded for drugs or illicit money on the streets. They are strictly and tightly controlled by the ATF and many states don't even allow law-abiding citizens to own them. So, why are you asking "why" someone needs a gun that has contributed to ZERO homicides? Why? I suspect you're talking about semi-auto rifles.
So let's dive into this a little deeper and apply some logic. Rifles are used in homicides roughly 400 times each year in the United States. Depending on what year's crime statistics you use, four hundred people are murdered by rifles...all rifles...not just semi-automatic rifles.
How many people are killed by drunk drivers each year? Go ahead, look it up, I'll wait right here. Surprised? Probably, because you're more into histrionics instead of rational thought. Since you have a Google tab open, why don't you go look up how many children die each year from accidental drowning in swimming pools. Go ahead, look it up (hint: the CDC maintains a tally). I'll wait here. Back already? Wow, right? Stunning.
So now that you've educated yourself, let's ask a very reasonable question: Why are you ranting and railing against guns when autos and swimming pools take 100x more lives? Why are you here posting silly questions instead of working to prevent tens of thousands of needless deaths just because someone thinks they "need" a swimming pool?
Go forth now and educate others. Share with them the folly of your thinking. Teach others. Unite others against the horrific numbers of deaths caused by automobiles and swimming pools. Better yet, start a lobby group: CAASP (Citizens Against Automobiles and Swimming Pools).
Oh, and be sure to thumb down this answer. Liberals always thumb down facts, reasoning, and logical thought.
