Please clarify - You are saying that equal access means ASL and SPOKEN language. If this is the case, I disagree.
What about deaf kids who can't hear speech, even aided to the max? Those who have no receptive access to spoken language? To force use of a method they are physically unable to access is rather cruel.
YES, I agree with equal access to language, both ASL and English, but speech is not included in that. Language does not equal speech. Communication does not equal speech.
Hearing/typically abled children do NOT have the equal right to language you assume they do. They get what the curriculum gives them and nothing more. They have no choices, regardless of their personal needs. Many, if not most, children would greatly benefit from sign in the classroom, but because they don't "need" it, they won't get it. Sometimes even if they do need it, they still don't get it because they don't need it bad enough.
