That’s a very limited understanding of racism and ‘othering’. Why, in your opinion is Rose not cool or attractive?
The Rotten tomatoes history lesson speaks of socio-economic engagement. I hardly see how it’s relevant to rampant western racism.
I'm not presenting a treatise on the basis of racism, or 'othering'. I'm saying that Kelly Tran's character was disliked for reasons that have nothing to do with her race, and acting on that dislike took the form of a variety of epithets - some racial. I'm sure she also got body shamed, but we don't say that the agenda of anti-fatists is to blame. While both are unacceptable, there is a difference between hating someone
because of their race and using a racial epithet to hurt someone you dislike for other reasons.
I think Kelly Tran is cool and attractive. I think that Rose Tico, like Poe and Finn, is a silly, foolish character that doesn't match the more handsome and competent aesthetic of Han, Luke, Chewie, Leia and Lando. If Rose Tico was a Jedi played by Lucy Lui, her Asian female character would have been a non-issue. Racism is not logical. Just look at all the casual racists who adore black athletes.
The flip side of this is that the Rose Tico character casting decision seems so out of place that some people are going to assume that it was made for reasons other than presenting the best possible Star Wars recreation experience - like a racial political agenda. And such agendas tend to also fire up the kooks who then react by going in the opposite direction and doing the one thing that horrifies the people with the agenda - bigotry.
It is a fundamental error to presume that the root cause of every racist act is racism. If two drunks get in a fight and one uses the N-word, that doesn't mean the fight started
because of racism. But there is a tendency to view all racism as the root cause of all of its effects.
The rotten tomatoes example just illustrates that an audience tends to channel their dislike of bad scripting, casting or direction at the person playing the part rather than the mysterious director behind the curtain. It has nothing to do with socio-economic anything, but just that stupid people tend to act out inappropriately to things that they
and their betters dislike. I can dislike Rose Tico for the way the character appears and acts without there being any racism involved in my feelings, and that somewhat disproves the theory that criticism of her is based solely in racism.
Please don't attempt to read some sort of agenda on my part. I'm just agreeing with
@KGeo777 that racist effects aren't always due to racist causes. Rose Tico is a cute teddy bear in a story about monsters. She didn't work. I'd enjoy seeing Kelly Tran in something that uses her qualities to positive effect.
