Yes and no, because nobody should be forced to do things against their will.
but because it shows that communication with you - a Deafie, is important to hearies and they'd do anything to try and make it as easy as possible for both of you, also shows that hearies find Deaf ways interesting -
it is deeply appreciated if a hearing family member go out if his/her way to learn ASL.
but you can't force it. not IMHO.
Last but not least, certainly for the Deaf people, if a hearing family member learns to sign this can be a huge way of showing his or her acceptance for the deafness and Deaf Culture.
perhaps this is even as important if not more?? the factor of wanting the family go ASL as an ease of communication...?
that's why this is such a hot topic...
Fuzzy
My opinion exactly I think if you have an immediate family member who is deaf than allowances should be made to learn at least some sign language.
