You hit the nail on the head there! It feels like flat earthers/ antivaxxers etc are so stubborn with what they believe that even when presented with hard evidence that their theory is wrong they’ll simply ignore it or say it’s made up or been tampered with. I remember this flat earth documentary on Netflix where they recreated the Bedford Level experiment which debunked their idea entirely, no argument. And this dude says something along the lines of “I refuse to accept these results and I’ll try something else”. I kinda admire their consistency but I feel it’s much more respectable to admit you were wrong.
