She was banned because of her political beliefs and her media work highlighting politically incorrect things. And the absurdity that they would use counter terrorism laws to detain her whilst fabricating some reason to deport and ban her. This woman does work against islamic terror, she is not a terrorist, she is the one fighting terrrorists. The UK let's 30 hear old Afghans who pretend to be 17 stay in the UK but Lauren who is a real westerner gets the criminal treatment.
I don't believe for a second that they consider her a threat to anyody's life. They are afraid that she will point out negative things about uk migration and asylum policy, they are afraid of her talking about problematic aspects of islam.
This ban makes is unnecessary and makes no sense.
