You know what's also disrespectful?
Forcing the rest of us to comply. Maybe I'm posting an image because words can't describe it. Maybe it's a technical drawing.
But these days..alt text isn't optional. It's forced. How the fuck am I supposed to do alt-text for a schematic. "This is a schematic diagram". What if the person has no concept.
How do you describe the color blue to a blind person?
Sometimes words can't work...and you're forcing us to use them. IT's a real WTF.
