Nothing in the article you linked appears to indicate that al jazeera is anti semitic. Nor does it indicate it's anti-Israel even. Certainly, it deleted a story, and didn't instead retract it, which isn't great, but how does that support an accusation that the entire outlet is anti semitic or anti israel?

Opposing Israeli war crimes is not anti semitic. Claiming that Israel represents all Jewish people worldwide, though, is anti semitic.
