I dont know why you bother, clearly you are preaching sense to morons.
Their only answer is I didnt see it with my own eyes so its not true.
For the rest of the world that resides in sanity, many of us have seen it with our own eyes so we know how stupid their responses are.
I agree with most that you say but there might be a few not so far down the "rabbit hole" that they might be "recoverable".
Your observation "Their only answer is I didn't see it with my own eyes so its not true" just so true.
To demonstrate this just look at
JM Truth quite openly accusing
Team Skeptic of lying about a video that
Team Skeptic had personally taken on site.
It's a 1 hour 28 minute video but the relevant part is near the beginning:
Reds Rhetoric VS JM Truth - The Rocket Launch ShowdownJM Truth simply cannot accept any evidence the does not fit his "Worldview", even video evidence presented
personally by the person who took the video.
But that's little different from most flat Earthers.
The Southern Hemisphere non-stop flights South Africa to/from Australia, Australia to/from South America and South America to/from South Africa do not fit the flat Earth map so some go to extraordinary lengths to claim that they are "fake".
