Make Sign Language (ISL) a Leaving Certificate Subject

I think that if you can learn Russian, Ancient Greek and Latin for your Leaving Cert then you should be able to learn a language that people born here speak as their first language. I also think that it would encourage students to learn Sign Language, even if it is just a non-curricular language that has to be studied outside of school.
If more hearing people could speak sign language, the deaf community wouldn't be so isolated in society.
