Which is why I think it's the wrong term, and why utxaa was confused.

Your link to Google for a dictionary definition says:

1) deliver a sermon or religious address to an assembled group of people, typically in church.

This wasn't a sermon or religious address, and HN isn't church.

2) publicly proclaim or teach (a religious message or belief).

Okay, so posting a comment on HN is public, which means we're all preaching? This doesn't seem what you mean.

3) earnestly advocate (a belief or course of action).

This is the closest. However, "this is all going to end in X12" seem far from earnest advocacy.

Your own comments seem far more earnest - are you not also preaching?

It's far easier for me to believe you simply used the wrong term.
