It would seem that no one "suffers" from an ASL approach compared to the oral only approach, correct? I think this is misleading. It's just more obvious that people suffer from the oral only approach because you're starting from high expectations, rather than low expectations. I'm not saying that ASL has low standards but it is definitely easier for deaf people to learn language through asl than orally. So I don't think its fair to say that people suffer from oral only approach and not ASL based approach because the truth is you only can see the suffering when someone fails to meet expectations. You cannot deny that there is a possibility that a ASL taught person may become more independent and confident in the hearing world if he was raised orally in an alternative universe. Honestly, when people tell me "Oh if he is so smart, then he will become confident in the hearing world ANYWAY. Being surrounded by ASL will NOT hinder it!". Sorry, I think that is bull because that's like saying "Well, if he's so smart, why don't you send him to any public school, he will do fine anyway." You'd have to be REALLY REALLY intelligent and mature as a child in order to take on obstacles yourself. We all know that as children, we do need a push. This is where the problem of oral only arises, the suffering is evident when the parents push too much.
Anyway, I rambled on there for a bit. Just saying that I don't think it's fair to say that ASL based approach doesn't have "suffering" because you just can't see it.
