I don't see anything at all in your comment that doesn't contribute to the discussion. The fact that you are downvoted on HN for just for stating an uncommon opinion is disgusting and extremely disappointing.
The current top post in this thread makes some claims that are disputed. It is possible to vigorously dispute those claims without having to accuse the poster of being an anti-Semite.
If you're asking why those posts are being down-voted: I can't tell you. There probably are Jew-haters who downvote anything pro-Israeli; I'd be surprised if there were enough of them to counter the corrective upvotes.
But the post you responded to accuses anyone who makes a post that is not fully in support of everything that Israel does as an anti-Semite. That's a poisonous tactic; it's one reason why political discussion is strongly recommended against on HN and I stand by my claim that it is why that individual post was down-voted.
Here are two pro-Israeli posts that are not currently downvoted...
