What has Musk done that's so bad?
He cheated the founders of Tesla out of their company.
He lies about the on sale dates of his products
He lies about the capabilities of his products.
He goes round trying to impregnate as many women as possible
He comes up with crazy transport schemes designed to do nothing more than sabotage sensible ones so he can sell more Teslas.
He has almost destroyed a perfectly good social media company, including sacking many of its staff and failing to pay them their legally entitled severance packages.
He doesn't pay his suppliers and landlords at Twitter.
He swindled Tesla shareholders out of money by selling his failing solar energy company to Tesla.
He propositioned a flight attendant on a SpaceX jet offering a pony for sexual favours.
These are a few of the bad things about Elon Musk I can think of just off the top of my head.
I know he called a good man a bad name (boo!)
To be clear, he called Vernon Unsworth a pedophile. That's slightly worse than "a bad name" especially considering he has millions of sycophant followers who will just accept his word.
and has suggested setting confused children on a pathway to a lifetime of self-deception and drugs is wrong, which some people seem to think is bad (I don't) but apart from that?
Even bad people can be right occasionally. Famously, Hitler was a vegetarian, but you don't hear any vegetarians saying "he can't be all bad: he doesn't eat meat."
