Did Gautama Buddha endorse the caste system?
Did Gautama Buddha endorse the caste system?


Of course not. There's a whole chapter in the Dhammapada where it shows what qualifies one as a brahman. None of them use high birth or high caste as the criteria:


  Whoever does no wrong
      in body,
      speech,
      heart,
  is restrained in these three ways:
      he's what I call
      a brahman. ~~ Dhp 391 ~~


About the Buddha being born in the high caste, we shouldn't blame Him for that. If any, the blame should be on the way folks treated one another in ancient India. It's simply a skillful mean to be born in whatever condition that is most conducive and effective in propagating the Dhamma. The Buddha was a Kshatriya and He already got all kinds of attacks from all kinds of religious sects. Now imagine being born an Untouchable in ancient India and trying to propagate a whole brand new religion, well, good luck with that!
