I’m largely indifferent to Musk who does seem to be a bit of an asshole, but not someone I care enough about to hate. I generally don’t think of him at all.
But I do dislike those kind of comparative arguments. On a moral scale I compare other people to myself, not other members of their peer group. Would I consider myself to be an asshole if I had called someone a ‘pedo’ groundlessly and went to the trouble of hiring a PI to investigate someone who dissed me? Yes. Then he’s an asshole. End of story.
That he may be less of an asshole than, say, the late Steve Jobs or Jeff Bezos (entirely possible) or certainly Donald Trump is neither here nor there. It just means others are bigger assholes, not that he isn’t one.
