"Flamebait is the posting of a provocative or offensive message with the intent of provoking an angry response" [1]
There hasn't been an angry response to this comment. In fact, they've been thoughtful, though some have disagreed.
I don't see how this is a generic tangent, since this comment directly expands on the post, and provides a Christian apologist viewpoint on artificial intelligence.
On HN, we don't go by intent (which is unknowable), we go by effects [1]βor rather, by likely effects [2].
The highly likely effect of posting a generic comment accusing other people of "hating on Christianity" is a religious flamewar, and that's what we got, with people accusing each other of not having read things (that was you, actually, more than once), being dicks, believing in leprechauns and orbiting teacups, and so on. This tedious stuff is not what HN is for, and destroys what it is for.
Your comment was certainly a generic tangent, as you changed the topic to the value of Christianity in general which is (1) as generic as it gets and (2) references nothing about the OP except that one point.
