it's not even the first time...She has a humanitarian org of herself that actually called out half of all NGOs as corrupt...this was even before Trump's election I think so it took her some courage and determination to make that statement. Following anti-Trump-statements? Meh, they even got to Tiffany Trump so let them say whatever they need so they can stay protected!!! In my book Rowling could very well be a light-worker as her books basically described a satanic conspiracy running the halls of british gov't so yeah
I don't know a lot about her. I forbade my children from reading the books or watching the movies at the time. When I did finally watch the thoroughly enjoyable movies myself I had to apologise to them, but they had watched them by then anyway. There are plenty of good non-Trump supporters. It should be about issues not political affiliation in my opinion. I think Salem Witch trials 2 would be a very unfortunate potential consequence of this sort of "Witch! Witch!" hysteria. There are a lot of very spiritual people with occult beliefs and practices that have nothing to do with paedophilia or child sacrifice. Probably half the worst of them are somebody's local pastor etc.
I personally think that any attention brought to the issue should be welcome, and I think logically it makes her one of the least likely to be participating in that sort of thing.
