The only time it bothers me at all is when it's using blind as a stand-in for stupid and not in a jokey literal sense. Like, "Wow you're blind, the cup's right there!" doesn't bother me. "You must be blind since you couldn't even figure this simple thing out" annoys me slightly, but not even really enough to say anything.

With the exception of when people imply that all blind people are stupid/cognitively impaired, I rarely give a shit enough to say anything.

I use it at work alot. 'Cmon guys even the blind guy could see it' 'are you as blind as me' it helps ease the tension people have about tip toeing around my vi

I don't mind blind being used metaphorically, especially when it's a set phrase or related to maths. I find it a little more bothersome when it's used extensively to mean ignorant or incapable.

On an amusing aside, the blind leading the blind is something that can happen and make sense.

As to blindness being regarded as an undesirable condition, I've no problem with that. After all, it is.

I don't mind it at all. In fact, the line: "I can see the future with my own eyes. You're eyes are blind to it" is one of my all time favourite video game quotes. Just don't take it to heart. I know it's hard. I felt like that once before, but my skin thickened over time and now I just take it on the chin.

Anyone can be hurt by anything. It all comes down to the meaning we play on words. Personally, I don’t like the phrase “even a blind man can see that.“ I won’t sit here and be out raged by it though. I can’t expect the world to adapt to me. I can only teach the world. At the end of the day, I’m still human and I do get hurt by certain phrases. I tend to like metaphors though.

how dare you use insights as the last line of your post. as a blind man I am offended by that.

but seriously: blindness is a disability, there are very few if any blind people I know who would say otherwise.

No, not harmful at all. I think all suffering or disability or infirmity or whatever else you'd like to call it is an undesirable condition. I don't really agree with political correctness, either as I find it separates, rather than actually helping. It's better to get offended by things that actually matter, like injustice, or corruption, or things like that that actually hurt people. I just laugh at blindness. Yes, it sucks, and yeah, it's not a thing that should ever occur. I'm sure any sort of suffering fits this category, but society finds all sorts of ways to justify pain or suffering as glorified, when it's really, at worst something that should not be happening at all, or at best an unfortunate artifact. A meditation teacher I heard once said there are two ways to grow or challenge yourself, suffering or just insight and logic and observation. I'll take the latter, thanks, when I get the choice.

I have always been interested in blindness as a literary tool, not quite the way you mention but more Shakespeare (King Lear), Saramago, etc. - used to express that someone isn't cognitively seeing something. I guess as far as more passing references it also doesn't bother me. Maybe the only thing that comes to mind is when someone who wears glasses goes on about how they are "so blind" or compares that to my situation.

not even a little bit.

this post offends me. HOW DARE YOU EVEN THINK OF CREATING IT! /S

I'm sighted but I have blind coworkers--on my first day I told someone "see you tomorrow!" and then died inside when my coworker replied ominously "I'll never see again." Then she burst out laughing. Obviously no one speaks for their whole community but I like how to blind people I know understand how sight-biased language inherently is ("let's see what happens") and just roll with it.

I think there's a big difference between that and something that uses the word blind in a weird way... an example is how we used to call shipping using a customer's return address "blind shipping" [this is still the industry term] but we decided that was weird and now we call it "stealth shipping," which actually makes more sense and doesn't equate blindness to ignorance

I don't like when people use blindness as a synonym to being stupid or ignorant. It also kinda pisses me off when people say bullshit like "she has a moral disability".

I'm pretty okay with jokes, but abled folks tend to be pretty bad at making them.
