"Oh man people are really mad at this person, therefore _the person must be right_"

You think that better arguments are going to convince people with this kind of reasoning?

Loads of people all over the place are just wrong. It happens all the time. And there isn't a moral obligation to respond to some wrong opinion over and over again.

People who think we need to have rational debates with flat earthers are not people who will be convinced by much. They are the 20% of people who think Bigfoot are real.
