Can I just mention something re 'if you don't like Scott, you're racist'? Not once has Scott's race and/or heritage been a part of or been incorporated into his character or story. Yes, Scott is played by a Latino actor. But Posey being Latino has no bearing or impact on the character, because his heritage isn't reflected or included in the writing of Scott. You can be racist towards Posey, but not Scott as character 'cause Scott is written as white.
Scott is absolutely coded as a white character. There is nothing about him that gives a voice to what I presume is the unique viewpoint of a Latinx teen in small town California.
This guy almost got the role:
That’s how white the character was written. The actor may be POC, but the there is nothing about the character that approaches meaningful representation.
