Your point is? Treat all 20 years old like children?

Misrepresenting my point to make it seem unreasonable is known as a 'strawman' fallacy. You just committed the cardinal sin of arguing on the Internet. You see, I'm not saying they should be treated like children. I'm looking to keep your retarded demographic alive because, listen closely kid, the people perpetrating the most violence are victimizing others of the same age.

What I am saying is that men in their early 20's are the most violent age group and as a result of that, they shouldn't be allowed to own guns.

Blacks are more likely to kill other black people and white people. Should we treat all black people as though they're all murderers?

Nope. Poor people are more likely to kill people. Unfortunately, black people are the most affected by poverty. This is a solution that has a potential solution.

Young men are flooded with testosterone (and inexperience) and as a result are more prone to risk taking behavior and poorer judgment.

Also, that wouldn't be acceptable in our society whereas changing the age limit on owning weapons absolutely would be.

Also, no. They don't commit more crime than white people. Unless you compare by proportion - which brings me to the next nail in the coffin of your retarded argument...

Besides the fact that 40 isn't even a majority.

Now, you're either fucking stupid (which I honestly don't believe you are because you used the word 'arbitrary' earlier (although you were wrong when you did say it) or you're playing stupid.

Either way, this is the internet so I am duty-bound to actually illustrate the fact that although 40% is not the majority, it's perpetrsted by a MUCH MUCH MUCH MUCH -deep breath- MUCH MUCH MUCH MUCH smaller percentage of the population. Just so you can't pretend that you don't understand, just a few people are responsible for a staggering amount of violence.

So eat that shit, biatch.
