This whole Noah Wyle hate campaign stuff is feeling veeeery much similar to the way neurotypical people treat autistic people who don't emotionally respond the way they expect or anticipate.
Yes the guy doesn't seem to have made many friends on sets and jobs. You know what he has done? Hyperfixated on ways to help the medical community and actors through strikes, the pandemic and has learned an incredible amount about medicine and even owns a company that produces fake blood for film sets and dedicates his time to promoting the struggles faced by people who work in healthcare.
I'd bet you dollars to donuts he's just an autistic bro with his special interests and his job and quiet home life and he doesn't understand what people are yelling about half the time and doesn't care to concern himself with it.
Yes one of the actors from the show isn't returning but that reflects the actual struggles of people to cope in the ED.
'oh but why is it the actress of colour who struggles and has to go?'
Dude EVERYONE on that show struggles. In fact the whole place is held together by the most capable women of colour, without whom the ED could not run. Robi himself is falling apart all season. Mohan leaving might be the most same and healthy thing for her to do because the healthcare system tends to chew people up and spit them out, it's to show how we lose good people because the work environment doesn't support workers.
I'm tired of us treating anti-social or private people like they owe the world an explanation. Since when is being a loner a major character flaw?
