"I use that term as his tribe did. His mom was outcast but he came back to kill an conquer those who dissed her, point was inter tribal love was taboo an shaka bussed that door."

As I understand it, Shaka was indeed despised as a child because his mother wasn't married to his father when he was born. But it was not taboo to marry or be sexually involved with someone from a different clan. In Zulu (or northern Nguni) culture it is the opposite. To marry someone from the same clan is considered incest.
