Israel is not synonymous with Jews. I would say you are Jew bashing by associating all Jews with Israel and Zionism.
I don't now what "tossing flash bangs" means. The IDF alleges they had one flame gun. But it's not the point, even if they had had guns, they would have had the right to shoot a bunch of IDF thugs engaging in high seas piracy in order to enforce an illegal blockade. This would be a defensive action.
