When my son was 7, I started reading Huck Finn to him. As soon as the word appeared on the first page, he stopped me and refused to let me continue, rejecting the book for its choice of language. Whether he would have appreciated the book at that age with cleaned up language, I don't know.

This seems to problem of switches. As soon as people see a word that they have been trained to see as inappropriate, they switch off. There is no consideration of context. When I tried to explain that the language was appropriate to people of that time and place, he rejected the answer.

If they want bowdlerization, let them read Classic Comics.
