Did you know that American sign language is not English? Turns out people who only speak sign language actually communicate in English with an accent and with non-native grammar because they literally speak a different language. Perhaps that's what we're seeing here. 🤷♂️
I can see the bits that could be asl syntax but it's all over the place. It's definitely not written asl, but I can see it as decreasing effort in one's second language to prove a point
Not sure about english specifically, but one of my relatives were in the school for blind and deaf children (or those which are close enough). The problem is they just can't teach them good enough and every child requires a lot more time that teachers can give. So it requires a lot of time and effort from parents to help them and not every family has resources to do it.
It's a language with native signers. If you're born deaf to Deaf parents you grow up signing and you don't really learn English until it's time to learn to read. CODAs (children of deaf adults) also often learn sign first because that's their parents' language
It has different syntax. Its not even based on English, it's descended from French sign language and is wildly different from English as a Signed Language and from British Sign Language.
