That's not what padraic7a posted, you can't do personal attacks here, and since it looks like you created this account just to do flamewar, I've banned it too.
The poster is criticising the actions of a state, that's not anti-semitism in any way. He didn't even say anything about jews or judaism.
BUT antisemitism == antizionism as it simply design to strip Jews from their own homeland. Antizionism is not part of a global anti nationality movement that says "Let's abolish the 57 Islamic countries, the 21 Arab countries and this one Jewish state" its one and only goal is to deny from the Jews what many other have.
The "homeland" reason is stupid. Religion should have no say in politics, including the founding of states.
Israeli people feel that anti-zionist effectively results in giving weapons and access to those who wish to use them, which means destruction and ethnic murder. Unwillingness the explain how this outcome is prevented seems to many as complete alignment with Hamas goals and effectively (indirectly) calling for the destruction of Israel.
Also it's not bad to criticize a state for dickish behaviour. That's not antizionism, that's calling a spade a spade.
Opposition can have various degrees.
