There is nothing wrong with a parent deciding not to allow their children to listen to a politician. Schools are supposed to be for getting an education. Part of what is wrong with our education system is taking time out from the essentials to listen to some politician. I don't like my child being forced to watch Obama's speech every year and if a parent doesn't like having their child listen to a politician (or any other speaker that is not essential to their child's education) then that is the parent's prerogative.
