I am part Jewish and not antisemetic, but some of the things she is saying are along the lines of what professionals have said - the woman appointed to investigate rape said that, after asking Israel for all relevant information and evidence and reviewing all evidence in existance, there was no evidence of organised or systematic rape, that there was very little evidence of rape at all (although there was no denial that it could have happened) and that some false evidence had been given (a family of a girl who had been tragically killed publicly said that the reports she had been raped were untrue, they knew this as someone had been in phone contact up to the point of death). I can't remember the woman's name but I could find out.
The reports of babies being beheaded were also shown to be debunked. There were also reports which showed evidence that some of the physical damage had been done by IDF (this is not to do with rape obviously) and that many of the burned victims were Palestinian civilians who had followed Hamas through the fences. Some reports said that some of the killing and potential rape could have been done by the civilian groups. There were reports from inside Israel by Israelis saying that their family and friends near the border had been calling for help from Israel for several hours before help arrived - this is what Charlie Kirk was saying in interviews in the month leading up to his death, and there was a lot of anger from some quarters that this was being said.
This is not to lessen the horror of the 2 year long hostage situation. It is more that the professionals involved felt it was important to be accurate about what evidence there is and what evidence does not exist or is lacking.
She also commented on "lebensraum" which is not permitted according to Jewish websites, as any comparison with Hitler is seen as antisemetic (even though the lebensraum ideology in fact originally came from America in relation to the colonisers' perceived right to take land from Native Americans, Hitler found this inspiring) but moving away from that word, there has been a lot of talk from Zionist quarters and indeed Trump, apparently, about a "Greater Israel" which arguably could amount to the same thing.
I think it is more important for everyone to focus on a two state solution and protecting Gaza from non-Palestinian property developer billionairs, rather than any partisan tweeting.
