Are you honestly trying to tell us you've never called somebody something mean? Never said anything you've later regretted? Give me a break, people are imperfect.
People are imperfect, but people who truly delight themselves in their own imperfections have a problem and aren’t role models. Give _me_ a break, after thousands of years of forming groups humans are going to forget how to toss the assholes out? Nope.
Saying he "called somebody something mean" is a somewhat reductionist way of referring to a months-long ordeal that included hiring a (fake) "private investigator" and trying to push his "findings" to the media.
If you or I spent $50,000 to smear someone because they weren't sufficiently servile to us we might face some social and legal consequences but of course the rules work differently for "heroes" like Musk with virtues such as money.
