Ok, so then what is the problem with Rose? I am confused what remaining complaints there might be.
People are mad that she stopped Finn from having a super bad ass self sacrifice hero moment like Randy Quaid in Independence Day.
The point, of course, being that kind of thing is stupid.
Also, about Rose being working class, she isn’t just working class. She’s the person behind the scenes who does the dirty work while the heroes do the hero stuff. And her class status is important because she is the only character who (at least explicitly) was oppressed by the First Order (well Finn was too of course but in a totally different way).
