Dear Editor,
 I am writing regarding the Editorial section in the newspaper. I typically enjoy reading the well thought out and well-structured opinion pieces you feature. The letters to the editor often spark discussion between my friends and me. The political cartoons don’t normally make me laugh aloud, but I enjoy their social commentary, nonetheless. However, from time to time, I find I don’t get the joke or the point.
 I don’t feel that something as serious as the housing crisis should be trivialized in a cartoon about Halloween. I also don’t think Fair and Ethical Treatment for All Animals (FETAA), and other animal lovers will appreciate the latest depiction of police harming a chimpanzee, especially without any context.
 The purpose of political cartoons is to take headlines and turn them into thought-provoking discussion pieces, not trivialize them into punchlines.
 Sincerely,
 A Concerned Reader
