I have a friend that is an actual ‘rocket scientist’(NASA) and I asked him about the ‘flat earth’ folks.
He just snickered and said “It is like putting mittens on an autistic 7 year old and then giving them an ice cream cone and a puppy, fun to watch and no body gets hurt.”
Good times and great entertainment! Anyone at any coast (pick one) can watch ships leaving and entering the horizon. But it sure is fun to raise peoples’ blood pressure. Course there plenty of man made flat places.
