It is too much to ask that I embrace delusionment and falsehood in the form of misrepresentation of the facts, the word retarded in relation to a situation, does not in any way shape or form have the same meaning as in reference to an individual or group thereof.
Furthermore, learning difficulty or mental handicap mean the exact same thing. What if we said that a golfer had a learning difficulty in relation to playing golf or a golfer had a playing handicap. Can this in anyway be proven to be a statement that is false?
We are discussing a handicap that affects ones mental capacity, how can someone be wrong for saying something, when that which they are saying cannot be proven to be wrong or false, except that it offends the sensibilities of those that seize upon it as a way to criticize and discredit others.
Your arguments lack any true grasp of the situation, if what I am saying can be proven to be wrong then by all means explain how that is?
