WDYM?

Only their new SW trilogy comes to mind, but in SW racism among humans was something limited to very backwards (savage by SW standards) planets, racism of humans towards other spacefaring races and vice versa was more of an issue, so a villain of any kind of human race is normal there.

It's rather the purely cinematographic part which clearly made skin color more notable for whichever reason, and there would be some racists among viewers.

Probably they knew they can't reach the quality level of OT and PT, so made such things intentionally during production so that they could later complain about fans being racist.
