That nasty piece of hate-mongering work is profiting from this utter, utter tragedy in my hometown. Although I think today is not the day, I do also think she should be boycotted as much as possible and potentially investigated for hate crime. 'Final solution' is pretty damned clear IMO.
She may have deleted that tweet, but that's part of her strategy. Plenty of people follow her in order to 'monitor' her, there are screenshots galore - it just means her message gets circulated and she has the excuse of having deleted it. She is therefore not the one putting it out there.
Until our laws catch up with the digitisation of modern life, I'm doubtful a prosecution could be successful.
Ugh, today is so awful and she's made it that little bit worse.
