I grew up in Myanmar until 23 and know what you're talking about. Those 'sayalays' follow a less stricter rules/precepts than a fully-ordained monk. That's why they are expected to pay respect to the male monks. Of course, there is no denying that it's a male-dominant religion, but it is no worse than Catholicism. Buddha, according to the Buddhist legends, appointed his step-mom to be in charge of female monks and they have established their own structure, which follows closely to the one established by male monk's structure (but with slightly less strict rules).
As an atheist, I am not going to defend Buddhism (be it Mahayana, Theravada or Tibetan) because they all have major flaws, and aren't very practical--in my opinion--for the modern society. As with most religions, there are good and bad parts in Buddhism and a lot of original teachings by Buddha have been 'tainted' by cultural reasoning (not to mention that even Buddha himself likely got a lot of influence in his philosophy from Hinduism and other mainstream religions in his time). Overall though, I have to say that Buddhism at its core is fairly benign (no eliminate-those-who-don't-believe-in-our-god's-teachings that can be found in old testament or Koran).
