You can have an illness and be an unpleasant person. Katie is clearly both. There are a lot of people who make a living out of their 'controversial'opions but manage to stay out of trouble.
If you have poor impulse control and nothing nice to say Twitter is not the place for you.
Katie could have apologised but she is the sort of person who never admits she is wrong even when she knows she is.
I feel sorry for her kids. This must have an impact on them even if they are not being made destitute they will have to leave their home.
I wonder what Katie's husband is like and if he tries to stop her doing stuff like this.
