Sorry Plato..I can't say I agree

So here I am......
3rd year of college and we have to study Western Political Thought where Plato features first. Our Greek philosopher's contributions to Political Science have been irreplacable. When I read his theories, I was amazed. How could a man possibly think so thoroughly? About every detail and every possible argument against it? No doubt Plato is a philosophical genius and he rightly deserves the place he has.
So far, I have gone through his Theory of Justice and Education. I can't say that I agree with all his points but I admire his thinking. I admire his thought process but not exactly his thoughts.
Somehow I feel that his Ideal State was harsh in nature. For him the Ideal State would be where each man did what he was best at doing. I believe in that but believing that every human can be compartmentalised as Philosopher Kings(Rulers), Warriors and the producing class with only wisdom, courage and temperance respectively dominating their minds is going a bit too far. Believing that only a philosopher king has the right to decide what the classes under him would do is rather unjust and unfair. To expect that the Rulers would only think of gaining knowledge, the warriors of dignity and honor and the producing class only of appetite is certainly erroneous. Man is a complete being with many sides and wanting only one part to dominate all the others stunts human growth and intelligence. It leads to a one sided development of the mind and body at the cost of other needs. A warrior may also desire knowledge and so may the producing class for that matter. What right does the State have to deprive man of his desires?
But more than any other theory, his theory of Communism of Wives revolted me. How could such a great thinker go to such an extent for excellence that he deprives children of a normal childhood? To say that human beings have some needs and the philosopher kings could freely go to any woman and the child produced should be given over to the State because nothing should hinder the king from gaining more knowledge, is rather cold and repulsive. I blurted out in class that it was disgusting in the middle of the lecture..hehe. Don't you think it is? In the quest for knowledge for the Philosopher Kings, Plato goes to the extreme.
But there are other theories which I have yet to study and I am looking forward to it. I agree to some of his theories and he is a genius in terms of philosophical thinking and social morality. But there are many aspects of these theories to which I simply can't agree.
