The way you describe the forum , Luke, seems to me that their ideas are very clear to those that they decide to jump-in, so if you allow me the question, what is the point of discussing with those people if there is no way for you to persuade them?
Since they believe in racial superiority they would find interesting to know the word in the mother of the languages, ancient Greek, which stands for "conversation".
The word is "synousia" and it means sexual intercourse and it says a lot on what the people, who practically invented dialogue, thought about discussions.
They wanted to describe a spiritual osmosis, something that is interesting and challenging indeed when you discuss with people who are willing to interact.
Would you care to come "so close" to such people?
Frightening thought...
