Being blind myself, I can't see that being offensive. After all, to be blind to the truth means unable to see the truth... which is accurate.

Most blind people understand that using the word blind is a standard part of the language, and don't mind it.

I don't think most people would get upset if you used the phrase "see you later". Although, if that makes you uncomfortable, you can use the phrase "catch you later"

I never even thought about this sort of thing until halfway through college, when people got comfortable enough to point out when I'd use the word "see" figuratively (all the time). English is just full of sensory figures of speech. I mean, we say "figures of speech" even though I'm typing this. Even if you've gained information nonverbally, you might say "I've heard that..." And the word "feel" gets used in so many ways that it almost makes it difficult to talk about touch-sensations (I am itching for an excuse to use the word "tactum", but it just doesn't come up as much as you'd think).

So, yeah, no, go ahead and use "blind" figuratively.

Now, people saying "metaphor" when they mean "simile" ... that awakens my inner pedant like most nothing else. Although people don't use "blind" in similes all that often, fwict.

This is more of a sighted SJW thing than an actually blind person thing. Most blind people don’t give a shit. It’s kinda like if you said to a person in a wheel chair “You’re on a roll!”, they’d likely be all “lmao tru, I tend to do that”.
I’m only legally blind though. Have you seen Molly Burke on YouTube? She *loves* blind jokes.

i've found that people with disabilities tend to be much less concerned with political correctness than other marginalized groups. its more important for us to be understood and included.

I don't love it in the sense that it makes it impossible to google blind-related stuff, because you get a ton of metaphors and Venetian blinds and so on. But it's so common that it's something blind people have gotten over so early they don't even think about it. In my experience it's sighted people who get upset about use of the word blind as a metaphor.

Yeah ... not offended in the least.
