I think this person's argument is getting mixed up in being against cancel culture. If this was some nobody on Twitter yapping dumb s*** and a horde of SJWs decided to dox the guy and cost him his job, then yes I'm against that.
But this is not what happened. This was from the mouth of the CEO of an MLB team, one of only 30 prestigious positions available in the world. He embarrassed his team and his sport. This cancel culture exemption stance shouldn't apply to people in power. If we let society go down this rabbit hole of unchallenged nonsense from people with power with no consequences, hiding behind the guise of telling it like it is and free speech, you're just going to get more and more Trudeaus and Trumps leading things. People in power deserve more scrutiny for what they say and do, not less.
