Hot take, I really don't give a f*** about what Morris said. A bit crude?, probably. But if that's the bar for cancelling its too low.
not-hot take, Japanese people have a distinct accent. I don't see how that is such a crime to note. Ohtani himself has this accent.
It's not like Jack Morris was using coded language to say "Be careful with this guy, he can really hit. But also he's lesser than us whites". It was just a dumb and inappropriate joke. If he is doing this all the time, fine cancel away. But dudes who talk for a living should be given some rope if something less the professional slips out now and then.
