cacs mad they made the velayrons black, but don't know grrm originally wanted to make the targaryens and everyone from valyria black before deciding against it.
this is much better than the alternative of all black people in the game of thrones universe being confined neatly into the Summer islands and absolutely nowhere else.
this was a necessary rectification. they literally want a world where all black people live within those tiny little specs at the bottom of the world that don't even show up on most maps for the series. all the rest of the world with those cool ass exotic looking names? Spicy cacs and asians.
