""I shudder at the thought of HN turning into Slashdot, where know-it-alls feel the need to hijack any genuine religious feeling or discussion by injecting the latest anti-religion meme picked up from the intertubes."
And I shudder at the thought of HN turning into a place where appeals for advice are met by "Turn to $Diety, who watcheth over us all". That something may be believed with high conviction is not a measure of its truth or validity or appropriateness.

" any genuine religious feeling or discussion"
But that is the point. HN isn't the place for religious discussion or proselytizing, no matter how heartfelt or (subjectively) genuine the belief in its tenets is.
As with politics, these circle endlessly and go nowhere. There are plenty of other forums on the intertubez where people of specific convictions can exchange their beliefs (or delusions) to their hearts content.
Theology of any kind is a bad topic to bring up on HN. And any organized religion's theological minutiae are just as valid (or invalid) as discussion of the FSM, which is a device contrived to expose the subjective nature of such strongly held beliefs.
I have my beliefs about the nature of the Universe (it is irrelevant whether I am agnostic, atheist or religious), but I don't proselytize them here or try to gain converts by pivoting off peoples misery.
So no matter how "genuinely felt" your religious belief is, please don't pollute HN with it.
