Pitch lumen
Pitch Lumen, Who's real name is Nathan (yes another one) is a biblical flat Earther, who suffers badly from persecution thoughts, delusions of grandeur and paranoid fantasy.
I think he is genuine in his conspiracy beliefs.
He has admitted that he needs to feel special and wants a group to belong to.
Pitch is much nicer than most flat Earthers, he even promotes charity, specifically a program that helps seeing impaired people.
He is master of contradiction, so much so, the phrase "contrapitchions" has been coined to describe his "arguments".
Here are some:
He thinks zooming in on an object will shrink and enlarge the object at the same time.
He thinks education is indoctrination while studying at a school.
He thinks that the position of Polaris is accurate on Stellarium until its viewed from the southern hemisphere, then it stops being accurate while still being accurate.
