I saw this exact same thing with 9/11 anons.

Enemies always throw the outlandish theories into the pot of real evidence to get people to ignore the real evidence.

Enemies love to assert "because you are <a slander name because you talk of real evidence to a real crime> you must be a flat earther"

<a slander name because you talk of real evidence to a real crime> = 'truther', 'anti-vaxxer', etc.

But on the topic of flat earth and this board: it's a topic for conspiracies.win
