Does art have to be beautiful?

In my opinion art is supposed to either express emotions of an author, be nice to watch/hear or be thought-provoking. Having this in mind, art doesn't have to be beautiful, but should fulfill one of criteria I invented. I also think, that we mustn't tell the artist what to do, because it may kill his creativity. Secondly, everyone has a different taste and maybe there is someone who actually likes not-beautiful works. To sum up, art doesn't have to be beautiful and can be made for different purpose than amusing watchers' eyes/ears.

What does mean to be a real man in 21st century?

There are very few features of a real man, that doesn't apply to women. Man are often stronger than women so they should use it wisely and in order to help rather than to rule over women. If he is a father, he ought to educate and be a good example for children. A real man is someone, who knows his advantages and rights and uses them for good.
