Actually sign language in different cultures are very similar. Sometimes even the same for certain signs. As the deaf culture has grown over the years, the language has changed a lot because some signs/languages were more accommodating to hearing people. Or concepts that only exist to people who know sound or the spoken language.
Some sign languages like “SEE” sign, is a representation of the English language as it is spoken. SEE actually stands for Signing Exact English. And that’s not fair to those that will never know the spoken English language, so why should they have to learn it?
