Fair enough - obviously I would not dream to speak for others, but I do think in fairness, that the majority of people use the site to convey points of view based on discussion, rather than simply thinking nonsense out loud.
Although I would stress that I think this is the majority ... !!
A tweet is a privately published message, not one put out by the Sunday Times or Penguin Books.
It reflects badly on the person, and not on an employer, that most people will not even make the connection.
I confess that I have never heard of Indian Knight and did not know who employed her until I looked it up.
While I believe that people should face the consequences of stupid things they write on Twitter, losing their livelihoods for an off message tweet is going too far.
I've never heard of her, didn't understand what she's on about -although after reading a few posts it would seem that she is advocating the assassination of Trump. Surely anyone wanting/encouraging the death of anyone should be dismissed from wherever they work? I remember that when I was a student, the Brighton bombing took place. The then president of the S.U. regretted that Mrs. T. had not died in the attack. The whole student body held a meeting and she (President) was forced to resign - 1st time I had taken firm political action. Advocating assignation is a 'NO' to anybody i.m.o..
