Adachi, thanks for your reply and your concern that I might take it personal (I don't).
I support the Palestinian cause regardless of who is leading it at the current moment, but that doesn't mean I support killing civilians at a concert, in their homes, etc.
So the protesters celebration of that does border on antisemitic, in my opinion. And the intimidation in the subway car was chilling (I saw a video clip.)
Yes, Germany is misrepresenting what antisemitism is.
