I can fully understand if that has no value to you, but that means our values are different. For you to understand my perspective, you have to use logic (which you are) and my values (which your not).
I agree with this statement, but we need to go just a bit further. If we introduce empathy into the equation, we consider more than just our own views. Do the values we each have work to suppress or subtract others that don't have a voice? At what point does our mild inconvenience or discomfort become a drastic harm to others?
When I first heard about Disney casting a black actor for the live version of the movie it struct me strange and unfamiliar. However, with just a bit more consideration I realized that, while it was different, it didn't change anything in the story. Further having a black actor meant that Disney was able to open up the role to vastly more actors which means we could be getting a better performance because the limitations of skin color were removed. Further, one of the largest lessons learned in our society from the original Star Trek TV series in the 60s was the representation matters. Men and women of different races and ethnicity were able to connect and aspire to the characters because they saw themselves represented on screen with (mostly) equal footing. I see the same opportunity here with the Little Mermaid reboot.
Why does our minor short term discomfort or unfamiliarity with a children's movie remake mean we deny others that leg up to work in the movie industry and for viewers to be seen represented?
