Well I for one don't think it's politics. I remember my own and brother's circumstances - our parents raised us according to the advice of medical and other professionals, and they in turn gave their advice depending on what was actual trend in the field. With my brother it was advisable to go with the deaf schools, with me- go mainstream.
Altough I must add these were NOT the only reasons we were raised the way we were, but it did had a big impact on our parent's decisison as what to do with us.
Another thing that is almost always overlooked among deaf - hearing people who don't have a hearing impaired person in their own family, have no clue about deaf and deafness. The same way a deaf (and any) person may not know about living with trichotillomania, and what to do with it. If one meet such a person one would be puzzled, even repulsed. Just because never ever met trichotillomania sufferer before.
Most professionals are like that - they have no in depth understanding of deaf culture and how succesful it can be at all because they don't have any liaisons with the deaf world. They are hearing, they live in hearing world and even if some do know 'something' about deaf community they still feel the best option is to hear - because they don't know anything else.
That could be the reason too, that whenever a professional is confronted with deaf child, not knowing any other enviroment than hearing he is naturally inclined to try his best at helping this child to survive in hearing enviroment.
But I think the awareness about other options - ASL, deaf culture - is growing and it is very likely that in the years to come the professionals will not only advise implantation but also participating in the deaf communities at the same time as the best option for a deaf child.
