If someone, especially someone who is visually disabled, asks for alt text for the benefit of the visually disabled, and you get annoyed and accuse them of being unreasonable, and they in turn get annoyed at you, it's *your* fault. Disabled people are not the party being vexatious in that situation.

It's generally bad to get mad at people who have legitimate needs advocating for themselves. If you just can't stand it, the block and mute buttons are there, and silence is always a free option.
