One word, three syllables to describe Duveneck's thinking: Pa-the-tic.
It seems that we are supposed to live in a complelely antisceptic world in every way. Human feelings, contacts are verbotten. What kind of society are we inculcating? How are children supposed to learn to differentiate between acceptable and unacceptable behaviors if everything is proscribed?
Even the oft-employed mandate that teachers are not allowed to comfort a child who has hurt him/herself? If a child feels left out because others are "touching" or some other inhumane, insensitive behavior, how do they learn about life and its unfortunate cruelties?
It's in the same mode as giving every child a prize just for participating. Please, get real......and have some sense of life. Life is NOT always fair. Learning to deal with it is fair.
