You just need to look at the Facebook comments on any official NASA post about Artemis to see depressingly many of them. Some are joking or trolling, I’m sure, but I don’t think all.

I haven't been actively looking for them, but a friend sent me something about the launch tower escape zipline/gondolas and how that somehow indicated something fraudulent. He is not a denier, but works with one and is always asking me to refute that person's claims.

I am fairly certain that Artemis II has proven conclusively that they were right all along and the world is flat.
