I’ve said this before and I’ll say it again but it is absolutely an example of civilizational inadequacy that only deaf people know ASL
“oh we shouldn’t teach children this language, it will only come in handy if they [checks notes] ever have to talk in a situation where it’s noisy or they need to be quiet”
My mom learned it because she figured she’ll go deaf when she gets old
My family went holiday SCUBA diving once, and a couple of Deaf guys were in the group. I was really little and I spent most of the briefing overcome with the realization that while the rest of us were going to have regulators in our mouths and be underwater fairly soon, they were going to be able to do all the same stuff and keep talking.
The only reason some form of sign language is not a standard skill is ableism, as far as I can tell.
For anyone interested in learning, Bill Vicars has full lessons of ASL on youtube that were used in my college level classes.
and here’s the link to the website he puts in his videos:
For BSL, I’ve been (far too) slowly working through the british-sign intro course, which isn’t free but is currently pay-what-you-can.
