Gender nouns

Is there a point in nouns having a gender? I was always told it removes confusion, ironically the opposite is true for me anyway.

Here is >21.
For me genders in nouns add some special cultural and emotional twist to common words. My native is Polish so we have genders for everything and sometimes to word with different gender for the same thing. The gender in nouns gives described objects also some property. It is quite often that masculine objects are less harder, more dangerous or just uglier than feminine ones. It separates the whole word in two categories plus who neutral objects. We got feminine hen and masculine rooster plus neutral egg because it can become either. We got feminine birch and feminine willow but masculine oak, because of it hard wood as opposed to former two. We got even feminine mouse and masculine rat. It really is much more than practical use. It is the whole concept of universe. It gives something like a soul to every object and a lot more.
For me English sound a little sexist. It is because in its structure seems to be coded a vision of the world in which everything which is of male, hard, strong and active is good and worthy of praise, as opposed to female.
