My son and I were researching a report on disabilities together yesterday.
We found plenty of information to support the thesis that the movement to respect and teach people with handicaps came out of the churches and morality teaching from Sunday School - so they could have the pleasure of reading God's word and be able to support themselves.
The humanist answer to handicaps was eugenics and Margaret Sanger, whose view was the disabled should be wiped out of existance.
No matter what they secularists say, their vision would lead us to a place where man is of little worth, not more.
And, you still care. We all need more folks like you. ;-)
