I suspect it is no coincidence that these posts have come to light when you read who has been supporting her. However, her posts were certainly ill-advised. Israel as a state can be rightly criticise but comparing it to Nazis is never going to read well and your point will immediately be lost in the comparison. Is it antisemitism or just offensive?
The problem is people who speak out and go against the grain to raise genuine issues of concern are also those who are generally less guarded in what they say.
