No, I'm implying that the post doesn't have enough context to say one way or the other. That said, I do personally avoid language like that for exactly this reason. Avoiding ambiguity is just good writing, and I've had enough "[marginalized group], right?" encounters to not want to give horrible people any notion that I might agree with them.
Actually, I think the post has plenty of context to make clear he's not going for anything antisemitic. Which is why I think it was reasonable to point out specific tropes frequently used in antisemitic writing.
