As a few people on here have said, you passed on a double yellow. You gave the wing guys something valid to bitch about. Etiquette doesn't outweigh the law, so your complaint about them not easing to the right doesn't stand up against their complaint. I'm not against the occasional double yellow passes, but I know they're illegal. So if I found myself in your situation, I might have leap-frogged my way through as we'll. But I probably would have just given them a quick "sorry about that" and went on about my business.
Also, new riders on big, massive Gold Wings shouldn't be riding anywhere that one or two passing bikes makes them nervous.
