This thread was in fact flagged for quite some time, so...
Even after being manually unflagged following user requests, the false flag will have impacted its rank in the HN algorithm.
For the record, OP is entirely correct to assert that anti Israel stuff is always quickly flagged here. I've seen it many, many many times. Very often it isn't ever unflagged, despite being extremely relevant to this crowd.
My priors inspired me to look if strenuously denying live-streamed genocide and repeating bad Hasbara are regular pastimes from your account. It gave me no joy to see I was correct.
