This seems to be conflating 0.333...3
with 0.333...
One is infinitesimally close to 1/3, the other is a decimal representation of 1/3. Indeed, if 1-0.999...
resulted in anything other than 0, that would necessarily be a number with more significant digits than 0.999...
which would mean that the failed to be an infinite repetition.
What an absolutely deranged claim. What is it that “SJWs” are advocating for that you think is invalid? Because if it’s something along the lines of “they should stop advocating for an oppressed group of people” you should really consider what it means to try to build political power. Unless you’re going for “if we give the billionaires more stuff, maybe they’ll let us have medical care, as a treat.”
