"Perhaps someone who has such narrow and specialized communication needs that they need to browse the web via email isn't in the best position to be dictating what communication methods the world at large should use".
Boiled down futher:
"What's good (and bad) for one person with specific needs isn't the same for everyone else".
You made nothing more than an ad hominem attack. First you wanted us to discount Stallman's argument because of...wait for it...the way he reads web pages.
Second you wanted us to discount Stallman's argument because "he's so far off the page from the vast bulk of humanity (in terms of how he communicates)".
Can't imagine how such a mess at communicating and someone so very far off the page keeps duping all those folks who keep inviting him to speak (as well as the folks who gave him the ACM Grace Hopper Award, a MacArthur Foundation fellowship, the Electronic Frontier Foundation’s Pioneer award, the Takeda Award for Social/Economic Betterment, andseveral honorary doctorates):
Mar 01, Madrid, Spain "Por una sociedad digital libre"
Mar 07, Sunnyvale, CA "Copyright vs. Community"
Mar 13, Republic of Singapore "Free Software and Your Freedom"
Mar 14, Republic of Singapore "For a Free Digital Society"
Mar 27, New York, NY "For a Free Digital Society"
Mar 29, West Lafayette, IN "The Free Software Movement"
Apr 03, Ashland, OR "Copyright vs. Community"
Apr 04, Ashland, OR "For a Free Digital Society"
Jul 10, Dresden, Germany "The Free Software Movement"
Some communicator.
Now. Do you actually have anything at all to say about Stallman's actual argument(s) in that thread? Did you even read them?
Do you know why RMS wgets webpages to his email instead of reading them through a browser like 99.999% of the web-using world?
If the answer is no, then you don't know if it's a need or a choice or some variation between the two - and I daresay you're accusing him of something untoward.
