The first two ladies I would say are the same just a reflection of her downward spiral.. the third is not, if you play the first 2 along side each othe r the tone of voice and content is similar.
Anyway, Mental health and addiction is no ecusse for this type of behaviour, I have known many people with addiction and mental health problems and none would spout this shit so it certainly is not an excusse for the views. The lack of inhabition possibly as posted earlier by many posters. however I would say she looks like she is on street drugs rather than other wise mentaly unwell. I think it is ignorance to blame her percived condition.
The woman has some issues regardless and her child is very vulnerable. Im glad she is arrested now.
