Debate raises awareness and challenges opinions. It's not related to the criteria, but it is related to why you would be inclined to discuss this on HN if you were inclined to discuss it outside of HN.
I don't need to know anything about your political involvement to draw conclusions about your involvement on this particular cause.
Edit for clarity:
When I mentioned the criteria, I wasn't referring to debate; I was referring to awareness.
I can see how tempting that would be, but David is a special case. With his many years of complaining about politics on HN he has covered the entire ideological spectrum. :)
Edit: I mean that to sound good-humored, not snarky. I agree with davidw on this more than I used to.
