Sorry, irishingenglish. It looks like I misunderstood you. It looked to me like you were telling me I should stop talking about it. A lot of people do that, and it's possible that I've become a bit reflexive about it.

I said discussing this on a forum with people with entrenched viewpoints doesn't help much.

This is where we disagree. I don't see what I'm doing as talking to people with entrenched viewpoints. What I see myself doing is correcting a lot of historical disinformation in a public forum that is read by a lot more people than just those with entrenched viewpoints. You and I are aware of the entrenched viewpoint people because those are the ones who respond, but I know for a fact that a lot of people read these threads who don't post to them.
