Right, there's a definition element and a proof element, but I'm just going off what I've seen from "0.999... denialists"
Usually they don't understand/know the definition, and often they seem to not know what a limit is, so that's what makes me say the difference has to do with definition rather than proof. I feel like if proof were the issue then they would be outright saying "0.999 ... is equal to the limit of the sequence (0.9, 0.99, 0.999...) but that limit is not 1" but someone who understands those terms would be very unlikely to say that
It has to do with everything and it is very tiresome because it pops up again and again. Some people just don't want to accept it no matter how many times it gets explained.
That's true. I feel like math cranks have got to be a weird symptom of our insanely individualist culture but I can't prove it.
