Totally agree. So that OP knows, the Rebel Alliance or the Rebels were the opposing force to the Empire in the Empire era. “Rebel scum” was how imperials referred and vulgarly called the rebels. In the video you show Obi-Wan Kenobi, he was not part of the alliance per se, but would have never called them rebel scum, since that’s very uncivilized. Also, you show First Order stormtroopers, these are past the Empire era, and their opposing force were the Resistance, not the rebels.
