Are you familiar with with what a logical fallacy is?
Oh yes. It's the favoured "proof" of the flat earthers.
I want to pretend you are just trolling but I think you might seriously not see what the problem is.
To be honest... yep, a little harmless trolling maybe. I've gotten sick of trying to have any sort of meaningful discussion with the majority of the flat earthers, and like a lot of round earthers here, I generally just pop in and out for a few laughs nowadays. I had hoped for a genuine, informed debate from the FEs along somewhat more in-depth scientific lines, but (as you know) the majority of threads just turn into slanging matches.
And I think you'll find I raised the point of logical fallacies several months ago myself in reference to many of the FE's bizarre notions.
It's now obvious that logic doesn't enter into the flat earth dialogue. Or maths or science or astrophysics or astronomy... etc. So it was naive of me to think—way back when—that they could.
