Hey bonehead, Helen Keller did NOT develop finger spelling for the deaf. It was around a LONG time before she was born. In fact that is what Annie Sullivan used to teach her how to communicate, she had to feel the letters.
Having deaf family I find this sort of ignorance to be a blight on so many fine people. Notice the facts about finger spelling:
"By 1720, the British manual alphabet had found more or less its present form.[30] Descendants of this alphabet have been used by deaf communities (or at least in classrooms) in former British colonies India, Australia, New Zealand, Uganda and South Africa, as well as the republics and provinces of the former Yugoslavia, Grand Cayman Island in the Caribbean, Indonesia, Norway, Germany and the USA."
Helen Keller leaned towards socialism because of her desire for fair play for blind people and people with disabilities in general. We know how well capitalism takes care of them. Its only the socialist aspects of societies, even "capitalistic" ones, who take care of the disabled. Give a great lady a break. Satanist? My ass.
Pay attention to the hands:
