Iirc the only one she did about the Holocaust was one about how Poland gets shit for having Auschwitz in it but Poland really didn't have a choice. I think she may have questioned the death count numbers from Auschwitz or in Poland total which retards like Spino jumped up and called her a Holocaust denier.She did some video about the Holocaust and I think she was either questioning the nature of the camps or the number of deaths there or some other Alt Right talking point. According to her that is what got her kicked, but I recall some people pointing out that she had already been suspended prior to that.
Whatever the cause however, she was already racing down this path and I very much doubt a completed PhD would have prevented her fucking up her life.
I have no idea of the timing of everything else.
