While they defend the globe, it is impossible for people to stay on the level.
This is not just a pun, but a fact that their reasoning is built on deceptions. Globe earth defenders think what is curved is actually level. They'll tell you that railroad line wraps around a ball earth yet remains level.
Just like they think water surface curves, but only appears level.

What's really surprising is that people have the nerve to defend such premises. Arguing that railroads are parallel to a particular line is an obfuscation. The track would still have to curve to follow the contours of the globular form, which it never does.
