I agree with you Reba. Older generation, like who's now in their 60-ties, 70-ties they have a whole lotta emotional, cultural and other baggage that prevented them from learning ASL then, so I seriously doubt they'll change they way of thinking today, although one never know.
I know where we were young, when my brother was young, my parents simply were so incredibly out of place in terms of Deaf Culture, signing,
anything deaf that it was simply unthinkable to try make them sign.
It was like trying to make a very conservative, traditional Christian timid people dress and behave like a pair of hard core Goths.
Maybe, if they were exposed to other parents who signed and other children who signed that would be different, but they weren't.
