I'm just gonna correct real quick, hope you don't mind, it was Genshin Impact where a cis actor took over the role of a striking non-binary actor. However Honkai Star Rail has also had recasts cause of strikes, so I get the mixup.

I don't think they will unfortunatly, it's not really a crime to state your opinion, no matter how bad of an opinion it is... but I do think he has damaged his career for the future.

I just saw the video and I don't know if this is actually a person with autism or someone acting in way they think people with autism would behave.
Either way a disability does not excuse stalking, EVER!
