I suppose their attitude towards women was to be expected since the Indians were Asians first. The Asians never did have a great attitude towards females.
They weren't the first Americans nor were they even Indians. Misnomers all around.
Using a broad brush to paint all Native Americans for the practice of one or two isolated tribes is very innacurate... they were not all one nation with a uniform culture but rather hundreds of nations with distinct cultures, languages, customs and differing religions -for example, ditching the elderly was not a widespread practice but an uncommon one usually found only in groups living in marginal territory under extreme conditions but seldom if ever among agrarian tribes... slavery was practiced by some tribes, some brutally, some with the ultimate aim of adoption to replace lost loved ones, and some never practiced slave-taking at all... some had egalitarian cultures while others had all-powerful unquestioned overlords... some were barbaric and some civil. In the eyes of some of the eastern tribes, the settler’s treatment of their own children was considered cruel and abusive. One southern chieftain who had been taken to visit Europe with the aim of awing and impressing him was asked about his thoughts on the royalty he met- he remarked that he was impressed by what he saw but noted that the European women smelled like alligators.
