I mean, you know how everyone carries a phone these days? If you use your voice, it could be potentially recorded.
So… we could just use sign language. Teach everyone sign language, use that whenever you wanna say something anti-government.
Its much easier to cover up cameras (or move out of sight) than to cover up microphones. And its unlikely people would want to leave their expensive phone in another room out of sight, so teaching everyone sign language seems like a straight-forward option.
Also, bonus: its very helpful for people with hearing problems if everyone knew sign language.


Sign language isn’t just another way of expressing English that can be picked up like learning a different alphabet or a secret code. It’s a full, independent language with its own complete vocabulary, syntax, inflectional system, etc. that takes as long to learn as any other natural language.
It would be great if more people knew it for the sake of communicating with the deaf, but as a means of foiling surveillance, there are many other approaches that would be more effective for less time investment. (Hell, you might as well learn a really obscure spoken language that would be less likely to be recognized or deciphered than ASL.)
It also isn’t a single language. ASL is different than LSF, LSQ, or even LSFB, etc.
ASL and ASL are also both different. One is from Australia and the other from America.
Yeah my daughter is studying ASL in college right now and have learned a lot about sign language recently.
