The "flat earth eclipse" image/tweet might be amusing yes, but the manner of delivery of the image and its associated tweet would seem to carry connotations of arrogance and sneering at ignorance - which itself would seem to be an ignorant act. One certainly characterises oneself by such a negative act.
We are all ignorant, and some of us more ignorant than others. Being possibly less ignorant than another is not of itself a rational justification for making fun of the others who are more ignorant. We are fortunate if we have had some education, as it can help to lift us a little out of our naturally grossly ignorant state, but it does not necessarily mean that that make us any "better" than those who have not been so fortunate.
As my mother once pointed out, when I asked her what one of my teachers had meant when she made a racist (racially bigoted) remark to me: (I didn't know what racist or bigot meant, at the time)
Mother: "Well, she may be educated with a BA in history, but only ignorant people sneer at others or are bigoted towards them. Congratulations. You've just met your first bigot. You'll meet more in time."
Me: "What's a bigot?"
Mother: "Go and look it up in the dictionary dear."
One suspects that the scientist Richard Feynman's approach might have been along the lines of:
"Yet is it far better to light the candle than to curse the darkness."
- The English Wesleyan minister William Lonsdale Watkinson is recorded as first having used this oft-quoted expression in The Supreme Conquest, and other sermons preached in America, 1907.
...because, as he put it: (my emphasis)
"We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on."
--- Richard Feynman (1918-1988)
