Many indigenous groups that tend/tended to live close to/within nature, rather than attempt to dominate it, were/are not particularly 'polytheistic'. Many Native American belief systems for example could fairly be described as 'monotheistic'. There are also belief systems that are not particularly 'theistic' at all. In fact many of the groups that live/lived the closest to the original human way of life (hunter/gatherer) don't have any elaborate conception of what we would call a 'godhead', whether one or many.
There are certainly examples of polytheistic cultures that are male-dominated, conquering cultures of the type categorised as 'semitic' by a certain someone on this board... except that they are polytheistic. And with plenty of female deities. Go to India or Guyana and find out about that.
Many 'monotheistic' cultures could actually equally well be described as 'polytheistic' if you count all the angels, exalted prophets and culture heroes etc. (Catholics being the obvious example). Many 'polytheistic' cultures could equally well be described as 'monotheistic' (eg. if you translate 'orixas' to mean 'angels' or whatever rather than 'deities'... in fact most polytheistic cultures have a creator 'god' figure above and beyond the other 'deities' (in some cases male, in some cases female, in others both/neither, as in Mawu-Lisa in West Africa).
There is no hard and fast distinction between polytheistic and monotheistic, 'semite' and 'non-semite'. It is a vast oversimplification to say that these are "the two types of people in the world."
A better case could be made for saying that the two types would be the few remaining hunter-gatherer societies, vs. everyone else. The original way of life, vs. what came after and in many cases attempted to erase and destroy that original way of life.
Both these 'types of people' contain a mix of more or less 'mono', poly' or 'not particularly theistic at all' types of cultures.
