I haven't read this article as the topic doesn't grab me, but sometimes I agree with Katie Hopkins and sometimes I disagree with her. Depends what it is she's on about. Sometimes she's very right and sometimes she's very wrong. It's ok to agree or disagree with her, no need to compare her to Hitler just because you disagree with what she's saying. Free speech.
I like her robust approach to parenting, for example. I like that she doesn't do fussy eating in her house, I strongly agree with her on that. I like that she shows both her strong side and her vulnerable side - when she writes about her children I identify completely and find her very moving. When she writes about immigrants I disagree with her very strongly. But I agree with her about the general wussiness of society these days and holding onto what matters most (family).
She's a woman who's not afraid to wade in there. I think she was in the military at some point - you wouldn't expect her to be a wilting flower. She'd be less harshly judged if she were a man. Kind of like Mrs Thatcher. I'm sure she's not surprised that there are people who hate her.
