I think he should of gone less on the outright derision, more for the humour. When you are shooting fish in a barrel it's a bit crass to shout insults.
Look forward to the rest though.
There are quite a few series on this theme.
Many contain good material, but I rarely quote them, partly for your reasons, but also for the excessive use of foul language.
I know many here might use said language, but would still ignore a video against their beliefs using too much of it.
A few of these series are:
"Jeranism- FLAT Wrong!" by
Reds Rhetoric "The Earth Is Flat, Rory Cooper Says So! Part I: The Polaris Conundrum." by
Mahrai Ziller "The Earth is Flat, Rory Cooper says so! Part II: The Horizon" by
Mahrai Ziller "Revisting the Pole Stars Conundrum" by
Mahrai Ziller "Flat Out Stupid, The Jeranism Files: Episode 1" by
SciStrike ! - long!
"Return of Flat Out Stupid: SpaceX" by
Flat Out Stupid - The Jeranism Files: Antarctica - long!
Some contain useful information in "The Horizon", especially about
not rising to eye-level.
