The flat earthers are why I hate astronomy.

It’s not really about this particular claim. It’s that I can read a comment that has a reasonable chain of logic and I don’t know if it’s true. This topic is just not easily studied and theories are hard to falsify.

Claims about flat earth are falsifiable with at-home experiment.
