Black people in a realistic space age setting doesn't make sense since it implies the conditions on a planet have reached the point where the entire planet has had shelter from the sun for numerous millennia thus everyone developing the mutation for less melanin. Not everyone would be white, but almost everyone with black people in their DNA would be light brown. Though it could be argued that unless you got the best of the best of UV shielding people could develop blacker skin again.
You can see this in 'Murica today.
Star Wars is space fantasy, like WH40K or post JJAbrams Star Trek (unlike pre JJAbrams Star Trek, being science fiction that had space fantasy episodes that weren't the entire focus of the show) so complaining about black people in them is retarded.
I don't care for trans people, as I see them as people. They could exist anywhere.Also, I hope John Money gets raped in the urethra for eternity in Hell by a demon with a jagged glass cock.
