Yes, it's worthy of a ban, because you kept perpetuating a religious flamewar after I'd just asked you to stop doing that.

The other user was also at fault, and I've asked them not to do that in the future.

The reason I've banned you while merely warning the other user is not that I'm taking their side. Rather, it's that we'd warned you multiple times, including recently. That is not the case with the other account. Also, your account has a longstanding pattern of doing this over and over again. HN is not the place for this sort of generic flamewar, whether about diet, religion, or anything.
