It's a comic. By its very nature of brevity, it has to take an oversimplified view of a topic. That viewpoint expressed could even be radically different than how the author actually feels, but he ran with the concept to stage a joke. There's always someone, somewhere who will feel offended by anything a comic does. Don't take it personally. It's a comic!
