Ah yes. A famous best-selling author featured in the BBC is completely censored and her career is wrecked because... she got some angry tweets? What are you talking about?

As far as a career goes, at some point expressing an opinion crosses over to creating a hostile work environment.

As far as people yelling at each other online goes, you can’t really stop that. If you want stronger moderation, then people will complain that the mods are censoring them, if you want weaker moderation, people will complain about all the other people shouting at them. Not sure what the suggested solution would be. Perhaps the author wants the platform itself to favor her opinions specifically?
