In a very difficult topic you are thinking. I'm not sure whether we should limit Plato to such a type of teaching. Plato's political reasoning seems to me to be something that is not serious, his value is elsewhere. Irrationalism and Intuition of Incoming Christianity, Idealism. Removing the rational for me also has a positive side that is mystical and gives a claim that it is more than life. The rational enslave, cripples the imagination, and makes the person poorer. If you read "Candide" by Voltaire and the final of this work, when he comes to calmly and deny the imagination, this is for me an aristotelian ending. Yes, if we see the irrational from its political point of view, then it is pure evil, it only generates totalitarian regimes and deprives individuality.

Thank you for the comment. :)
