BULLSTALIN, them and their parents loathed America, the White House, et al when Bush was president. They are NOT incredibly patriotic. They support a man who jeered at flag pins until he became President.
It is a unfair to claim that the parents hate America. You have no way to know that. The kids wrote the letters to the president from school. This is just a school project. It has nothing to do with the parents or the performance of the president.
