I think, the best thing we can do is just wait. Just wait for companies to decide it's more worth it to take advantage of the moon and the costs go down, and it becomes safer to send people into space. When space flights for normal people becomes commonplace, the reaction from flat earthers is probably going to be diverse, but once they realize their mistake I don't think they should be laughed at for it. We should try and help them, then, because it is very difficult when your world is turned upside down, to maintain your sanity - even if they laughed at us when they didn't know, like they are doing here, we need to be the bigger person.
