formal letter grammar check

Dear redaction of New York Times,

I am writing to you in connection with the last article that appeared in New York Times. In which it was said of the behavior of today's youth. Most of the arguments given by you was against. Yes, I agree with two of them, namely, that young people behave very bad and they spend too much time on the computer. These arguments are very related with each other, because one may be the result of the second. Through the games and other internet activities teenagers became less obedient to their parents. There are also arguments supporting our youth. They do many positive and useful things. For example, big group of young people organizes a various collections for poor people or helps the older. sick people do shopping. And I dont agree with arguments saying that teenagers are aggressive. Not everyone is bad and aggressive. In order to convince you about that I would like to invite you to our school, in case to see what young people can be and how helpful they can be. Most of our youth are trying to change for the better and to change the negative opinion about them. You will be able to deduce from the interviews with students. I hope our students will make a good impression on you, and the next article will say about this situation from other point of view.

yours faithfully

can someone tell me if this is good ? eventually what should be changed ?
