Why are so many Americans utterly convinced that the Earth is flat when they can literally walk outside and see pic related?

Who keeps pushing this meme, and to what nefarious end?

You have awakened the horde

How much are you paid to spam this shit day after day?
Is it really worth it?
Do you think your parents and grandparents would be proud of you for doing this?

Lying is an act of faith and submission to Jesus and so christians are naturally drawn to bald-face lies like lying about the shape of the fucking planet.
And of course by christians I mean protestants. I'm not talking about pagans LARPing as christians by adopting a handful of their religious practices (like fucking children).
