Yes, it must be the case that not every child loves preschool. And I would expect parents to deal with it at the individual level, so if a particular child found it traumatic then the parents should trust their instincts and withdraw the child if they thought it might have long term negative effects. I wonder if the usage of the term preschool is important. In Australia this refers to the child care that happens immediately prior to going to school. It typically goes Kindergarten -> Preschool -> School. Wikipedia seems to imply in the US that it goes Preschool -> Kindergarten -> School.
