Could you please correct any mistakes, thanks.

Dear Editor,

I am writing in response to the article about the young people of today and would like to share my views. Whilst some of the opinions expressed in the article may fit some youth stereotypes, it is a gross understatement to do such a sweeping generalization on this subject.
First of all, although my generation, the millennials, are regarded as superficial and materialistic, the columnist should be aware that this statement does not englobe all the youth. Most of us are highly concerned about our duties in our everyday life, and therefore work hard to fulfill our goals.
Having said that, it is true that young people often spend more time watching television and surfing on the web; albeit this does not mean we do not enjoy reading books or getting out to exercise and stay fit. In fact, young people are more concerned about their physical appearance than elder people do. That is the reason why some illnesses such as anorexia and bulimia are more widespread among young people.
With regard to the internet, it is a double-edged sword. Information nowadays is more reachable than ever before in history. You can read whatever book you want and take it everywhere in your e-book reader.
Furthermore, I strongly disagree with the writer's opinion about fashion and materialism. Fashion tendencies change every year and it is not constrained to young people, meanwhile materialism permeates all age brackets and it has a social background rather than being a youth-only issue.
To sum up, columnists ought to be aware about the risks of generalizations on this matter. Not only is a trivialization to do such broad judgments about young people but also denotes blissful ignorance and lack of tact from the writer.

Yours faithfully,
Felipe.
