No amount of evidence will convince people. The vast majority are married to what they believe is their origin and trying to convince them otherwise, in my opinion, is a fool's errand. Majority of these conversations aren't based on not having enough facts, or having too many facts.

Also, you should frequent HN's IRC channel. You seem to create a lot of mostly off-topic threads that pose a single question in an attempt to create a discussion and I think your goals will be better suited to the channel.
