Polemic isn't really the right word. Exploration is better, but one has a sense that MacCleod has ideologies in mind, has strong opinions, but is a good enough author to explore all sides. He's also a good enough author to allow the reader to decide which of the many ways is better or best or irrelevant—to the extent of an almost complete absence of denouement in this trilogy. I looked for a 4th book, but there is none.
It's about humans, culture, society, religion, economics etc played off those of various alien races who (as usual) are less complex than you humans. Still it works. It did make me think about my well-in-the-groove opinions about such things.
Many will find this trilogy unsatisfying, especially for those looking for escapist genre fiction. The lack of resolution or tying of any of the many loose ends will be annoying at best. But, true to life, there is no denouement.
