I really didn't think anyone needed to learn that homeless people aren't swanning around every major city dining on hot meals three times a day and overwhelmed with choices on shelter and resources. In my experience literate people who argue otherwise are deeply committed to a false worldview and information is no more going to change their minds than a high school science course might change the Westboro Baptist Church.
