I don't think there's fear, I think it's a matter of availability and cost.
From what I've read of FJ, it sounds like she fought long and hard to get ASL integrated into her child's program from the start, against enormous obstacles. There was no bi-bi school that provided both ASL and spoken language available (FJ, correct me if I'm wrong there, please).
My family is SO lucky to have access to a wonderful bi-bi school that provides an auditory access program specifically for cochlear implant and HA kids as well as ASL immersion. We just have to keep a threshhold of these amazing little kids in the program for it to continue. Tough, against some of the negative preconceptions about what kind of child gets 'dumped' in a school for the deaf and the costs. It's early education, but the level of education my daughter is getting is as good or more advanced right now than I see in any of the toniest of private school preK environments. She's thriving, speaking, hearing, signing. We've chosen a school for the deaf that provides her with the best possible access -- for her -- to the full educational experience AND language instruction in 2 languages.
But, like any private school, it's enormously expensive. My local school district is paying $60K+ every year to send my daughter to this wonderful school. How long will they (and our neighbors paying the taxes to support this) assume that burden on the school's budget? I don't have an extra $60K a year in my bank account to send my 4 YO to private school if they decide to cut the program and offer her instead an itinerant TOD/aide and accommodations (seat up front, tennis balls on chairs, carpeted floors and an FM system) in their mainstream classrooms -- or no accommodations at all depending upon how they interpret her testing (and whether or not I can discreetly flick off my daughter's CIs just prior to the test
) .
I think this combination of access to an ASL+spoken language+rigorous academic program AND a subsidized or free ride is very rare. And I thank my lucky stars every morning when she delightedly steps into that van to the school she loves. If it were available, I think you'd see a whole lot of pick-up among those who have only the oral-only option right now.
