Seeing people fancast Heathcliff as a white man infuriates me actually like did you read the book you said you're such a big fan of? Did you notice all the times where it's stated that he possesses really dark skin and how the many characters associate his skin color with his violent/animalistic nature, do you know that this is racism?
I was stressed because I saw someone say that adaptations that rely a lot on his race deviates from the original source because, according to them, the book >exclusively< uses his skin color to highlight his violent/animalistic nature as in imagery and that this is a evidence of Emily Bronte's whiteness and actually, I disagree wholeheartedly and I think the many times where these associations happens it just shows Nelly's bias against Heathcliff (a bias she always had even before he was able to say a word when he arrived at the wuthering heights) and the abuse he's subjected to it's also correlated to his race.
Anyways, I'm reading the book (40 pages to go) so it's all very fresh on my mind and I believe that the book contains commentary about race and social class dynamics.
