As usual, terrible quality moderation. This post doesn’t cause flame wars and you missed like a dozen in this very thread that were posted before this comment.
As for missing other cases of religious flamewar, you may be right, because (as I just explained at https://news.ycombinator.com/item?id=48524299) we miss most of what gets posted to HN. We rely on readers to bring the worst posts to our attention.
But I'd need to see specific links to be able to say anything, and readers would also need to see specific links in order to make up their own minds about your assessment.
As I said elsewhere in this thread (https://news.ycombinator.com/item?id=48522679) it applies the same to any religion. We've banned many accounts over the years for flamewar against Judaism (since that seems to be the one you're asking about).
I realize it's hard to see bad comments failing to get moderated and not feel like the moderators must have a secret agenda about the topic you feel strongly about. But the reason is simply that we don't see everything. We can't read even 10% of what gets posted to Hacker News, and we mostly don't read the threads in sequential order.
In other words, if you see a post that ought to have been moderated but hasn't been, the likeliest explanation is that we didn't see it. You can help by flagging it or emailing us at hn@ycombinator.com.
You've broken the site guidelines many times and we've asked you repeatedly to stop. I don't want to ban you, so please fix this.
