I really loved the use of ASL in all of my classes - in my experience, I know that using ASL did
NOT lessen the quality of my education; I even had AP English with the instruction and discussions held in ASL. Of course, we were expected to know our grammar and to know how to write decent essays! That is not an issue, if we get a good foundation in English writing and reading early on.
Me too! People are often amazed to find that I can write fairly well while I don't have adequate oral skills. I rely on ASL primarily. Reading is always the key, anyway.
I remember when I was 6, I read a children's story about Mary and Joe having to run away to give birth to Jesus. I noticed the word 'bore' - giving birth in irregular past tense in one of the sentences. I used it in one writing assignment totally unrelated to the Jesus story later on, and it really surprised the heck out of my teacher that I used it correctly! :P Keep in mind that teacher used SEE as a way to instruct the students of elementary school age. I guess I almost always had 'signed' instruction save for one hellish semester of having been mainstreamed, and you certainly don't see me being 'slow' on grasping and expressing concepts in written English.
I, however, can certainly understand some parents' concerns in interacting with hearing people. Unfortunately, not all hearing people are as enlightened as these parents or any of us when it comes to interacting with a deaf child or person overall. That's why I think there is some value in learning the essential words. Just knowing how to say 'thank you,' 'please,' 'hello,' and 'goodbye' - all the words used for manners are good enough for me!
It is my opinion that insecurity and impatient attitudes often contribute greatly to the difficulties I have in my interactions with hearing people. I can successfully interact with hearing people if they are open minded enough to communicate in other ways like writing on paper. We have technology - e-mail, chatrooms, DirectVP, relay service, etc - to add to our success in interacting with hearing people.
