"My perspective on this is that a person with this world view has to spend time with the people of the race that they're against. And that you can't really do on an image forum."

This is a very good point. It's interesting because it could happen on an image forum but it would probably be hard to make it meaningful in the way that you describe (and that is so important).

I can't help but thinking the internet might at least be part of the solution though. So much opportunity for diverse groups to meet and interact.
