Should Flat-Earthers be debated or ignored?

[Sal]

There is a school of thought that says we should engage with Flat-Earthers in order to bring these conversations out into the open and not push FEers to the "fringes" of society, so to sepak.

I saw a similar sentiment in the Netflix documentary Behind the Curve.

I think it's possible to convince some "on the fence" of things  before they tip entirely over to conspiracy land; before they start seeing conspiracies everywhere.

There is another idea that these people are holding fixed beliefs that will never change in the fact of evidence or reason.

I think this is true for the dyed-in-the-wool hardline conspiracy believers. Just not the ones on the fence.

After having very few, but intense, interactions ith flat-earthers, I've ultimately decided that these conversations are not worth having. I think that some people are prone to conspiracy and will shout conspiracy no matter what happens, where it happens or who is involved. I think having some sort of ominous group to blame for the bad things that happen in the world gives some people a strange sense of comfort.

What do you guys think and why?

I haven't engaged with a convinced Flat-Earther in my time on the Internet, but I know they exist.
