@caiocgo @qgustavor @randahl @winkelmesser @gsymon - Hi! I'm from a family that carries a genetic form of blindness. While I'm seeing (luck of the genetic draw), about half of my extended family are legally blind, and most are visually impaired to at least some extent. I'm also involved in activism for people with various other disabilities, and live with a disabled partner. With those credentials out of the way:

I can genuinely assure you that when disabled people are "nicer" about an issue than non-disabled allies are, it's very often because they are a) too exhausted to keep fighting you, b) too depressed by the constant ableism they face to believe in themselves any more, c) genuinely afraid you will do them harm if they try to stick up for themselves, or d) embarrassed about being disabled/needing something and don't want to draw attention.

Allies tend to have more energy to stick up for our disabled loved ones, because we aren't also dealing with the daily challenges of, y'know, actually being disabled.

"Bad" alt-text is still better than no alt-text, and you'll never get better at writing it unless you practice. And using limited time and energy to ask someone (who might ignore you, or even respond with hostility) to do what they should have done in the first place? Takes way more time and energy than just re-posting with passive-aggressive captions.

The shame you feel when you are called out for not posting alt-text is nothing compared to the shame of having to constantly ask for help and accommodation, drawing attention to yourself and your disability.
