Using "zionist" as a derogatory term makes you a racist in a first place. And, because it shows your hatred towards jewish people, it make you anti-Semitic.
You just throw in anti-Israel propaganda regardless to what I've just said. Any comment will do. And this is going beyond accusing the state. You say "zionist talking points", - this is a pure anti-Semitism.
From the article: - "The attack on this building was part of other offensive operations that took place after Hamas was alleged to have fired rockets into Israel over the weekend."
"Alleged", right, there were aliens firing rockets on Israel. There is nobody else to fire the rockets. Only Hamas has them. And placement of the "offensive" as a response on firing rockets at the Israel's civilians. Looks like this is very offensive to protect your civilians!
