If Thork doesn't want to discuss Wallace's relationship with the Flat Earth movement, then perhaps he shouldn't have started the thread in Flat Earth General. If he wants to discuss its merit as a documentary, then Arts and Entertainment would seem appropriate. If he wants to discuss Wallace's scientific contributions (outside of FET), then Science and Alternative Science would be appropriate. If he wants to discuss Wallace as a person, then The Lounge might be a good choice.
My point is that there boards that are much more appropriate for that thread. Even though FEG isn't necessarily for discussion of FET, it is still where Flat Earth General topics are discussed. If Thork wants to have a non-FE Wallace discussion, then he should do it in a non-FE board.
