Is this a defense of cancel culture, or saying that ruining someone's career is in all cases appropriate since they must have view X which they wouldn't share with an employer? It's actually rather hard to know the views of people who've been mobbed on social media, since millions of other voices drown them out and make assumptions without them having a proper chance to defend themselves. Moreover, an employer may believe such a person to not hold noxious views, and still find them unemployable because of the social media backlash. Are you seriously arguing in favor of mob justice on the basis that the victims of internet mobs should be happy to not be employed by someone they disagree with politically?
