Counter argument:
Yes, at the age of 18 you probably do get more responsible. But, a lot of minors are out there in the world knowing that these people are making the wrong choice.
They should be able to take part too. Adding on, life is all about learing to push harder and keep on going.
People make mistakes and as a person myself I definetly make a lot of mistakes. But, what if kids were able to learn at a young age. Of course they might make mistakes.
Non the less, that is what life is. If there are to be any trouble the goverment would be able to just stop it, so there is no harm done.
Yes, my oppenent has a point, but to make this world better kids should be able to learn from their mistakes. To know what is wrong and what is right. That will lead out next generation to be better and better as it goes on.
