This is, in my opinion, low content posting. Especially when BiJane herself makes equally baseless claims in regards to RE science with no citations.
Oh come on, what were you expecting?
I have been warned once for use of that image (though I'll admit, intentionally, it was never a serious point). Otherwise, I use it facetiously in less serious discussions (see: the 'is JRowe omniscient?' thread). Generally I gauge how serious to be by the degree of conversation going on in the same thread. In, for example, Heiwa's challenge thread, it's devolved into no more than goalpost moving, that's long since stopped being a serious topic.
The image is used simply because it's a more entertaining way of saying "Evidence please." In my opinion, it just looks better than having to repeat the same statement.
The difference between our two cases, is that evidence for RET is readily accessible. Evidence for FET is limited exclusively to a couple of websites with dodgy search functions, where looking up something will likely also unearth a refutation and will almost certainly find a contradiction, if indeed anything is found.
For example, if you look up 'The Coriolis Effect' on Google, you can find pages and pages about it. If you look up 'denpressure', you get this site. Like it or not, Flat Earthers needs to be willing to provide more evidence for what they say, because said evidence is not easily accessible.
Do as JRowe has done: he has a whole thread in the information repository that explains his theory. If you'll notice, I don't think I've used the image at him, because I know where to look for the justifications of his claims. You can't refer to 'legitimate FE science' when there are multiple interpretations of what that means and no accessible way to verify your claims.
