‘Don’t judge a book by it’s cover’ is one of those phrases that boils down a concept to the point where it becomes silly if you start actually considering nuance for a second. The outward appearance of anything is going to be your starting point for judgement. If an apple is a weird color, seems soft, and smells odd, you’re going to hesitate to eat it. Or if a book has a swastika on it you might think “hey, this book might have some confronting materials in it”. The phrase should probably be ‘don’t judge a book solely on its cover’. Kind of encouraging people to look beyond a first glance and give things a chance they might not otherwise. Ultimately the goal is to remind people to be open minded.
Speaking of open mindedness I hope you’re open minded about the idea of supporting my work via the links above. Every little bit helps me toward my goal of becoming the comics overlord of the internet. A role I promise not to abuse.
