Red hates you. It doesn't matter what people say. You're pretty damn sure he hates you. It was normal for Red to not speak, yes, but he answers other people when they try to talk to him. He just blankly stares at you before walking away or ignoring you!

Maybe it's time you ask him what his problem is. Red doesn't seem to like confrontation, but you need to know what you did wrong. Why does he ignore you? Why does he hate you?
