Blind accessibility vs. 'dumb arse' — math burns included

Robert Lewis confidently dunks on someone for including image alt-text, apparently unaware that alt-text exists for screen readers and accessibility, not as a cosmetic flaw. Glasgalf (verified author) responds with surgical precision, explaining the actual purpose of alt-text while roasting Robert's knowledge base with a crude mathematical insult. It's a beautiful collision of someone being catastrophically, publicly wrong and getting demolished by someone who actually knows what they're talking about.
