Felt the need to chime in since I saw no one talking about this: ASL (or, rather, the Brazilian equivalent of it, LIBRAS).

It's mostly due to being something really different (the grammar is, sometimes, somewhat, kinda like Japanese?), and doing stuff like communicate with someone in a very loud club over a distance (did this, was really fun!).

I say this, mostly, as perks that are less obvious than being able to strike conversation with deaf people. But this is the most important part.

Also, it let's me better understand deafness and deaf culture, as well as accessibility and how people often suffer under capitalism, mostly on what may or may not be classified as a disability.

I don't remember if we have a quote from Helen Keller, but she as a great comrade on her own right, denouncing the horrors that capitalism subjects people's bodies, and how that should end.

For those who do not know, she was deafblind from an extremely young age, but coming from a very wealthy family, she got a 24/7 tutor. She even got "oralized". Media picked up the "miracle worker" and the "overcoming her disability" story. Then, when she radicalized, the media took her out of the spotlight.

Anyways, it's been real fun!
