By the way, about Witsit himself --
I recommend his videos on Flat Earth. He's very smart for his age (about 32). He clearly has a high IQ and has done a lot of research. Furthermore, he has a skill at debating and he's willing to bring public attention to Flat Earth. That doesn't mean he's perfect however.
He fell for the "Jesuits/Catholic Church is the bad guy" BS. Long story short, much of what WE would ascribe to the Jews, the ѕуηαgσgυє of Satan, he would ascribe to "Jesuits" and "the Catholic Church". He has some vague belief in a Creator, but he's not even a straight up Christian (protestant). He thinks there's something to Scripture, but he doesn't believe "what most Christians believe" about Jesus.
And although he understands a lot of the high-end topics better than me, I would have him beat on things like history, religion, Latin, English language (etymology, pronouncing "big words", etc.) So as I listen to his podcasts, I vacillate between "wow, he's got me beat" and "man, I need to help him out!" A final criticism is that he's a bit of a wigger. He likes hip hop and is able to freestyle rap (which is an impressive skill, but not my cup of tea). He's also a product of one of the younger generations, and he identifies as very "cool" so he uses all the modern slang. But most of these criticisms would apply to all men his age.
That having been said, he's put out a lot of good videos on the specific topic of flat earth. He's not a worse choice than David Weiss or Eric Dubay. None of the major FE Youtube personalities got religion correct. Finding the true religion seems to be a real stumblingblock for "freethinking truthers" it would seem. Maybe there's just a lot of anti-Catholic propaganda in the Truth community (internet), so most truthers suck up the poison at some point...
