She is a user of social media, so must have known how social media is.
She misjudged going public in the first place, and she misjudged public reaction, both to her and the situation.
If she is now not going to be instructed by solicitors' offices, I can sort of understand it because they would not want someone who misjudges both herself and situations.
If she is going to fight sexism in the industry, in my opinion, she needs to handle it in a bit of a more private way, and different ways. Though she is young, so has time to learn that.
If you want my opinion - you may not - if you said a woman doctor had behaved unprofessionally and it was true it's just a fact. If you decided to make comments about how she looks in the photo of practice doctors in the waiting room it may be, particularly if you are using it as a tool to decide whether or not she is professional or unprofessional
If a doctor has a less than professional picture in their waiting room, I would consider that unprofessional.
