It means I debated very often with weird people and the proof that I did, is that I don't feel the need to make the poster above believe, that I actually did that.

(Otherwise I would have shared links where you can find me debating the topic at length with various people)

Because indeed, most flat earthers are immune to reason as they are in the realm of irrationality. So at some point someone needs to accept that and that helped my attitude towards my need to correct wrong information in people in general.

And if you believe now, I am a flat earther, because I said I discovered some flat earthers that act somewhat scientific sometimes and are open for arguments, well, so be it.
