I think you're being very generous to him there. Let me don my devil's advocate hat here; let's say he was, as you say, ignorant as to the meaning of his actions. Okay; fair enough. But why, then, did he choose that particular celebration, as opposed to, say, doing a funky chicken dance? Or something equally "wacky" or "zany". I think he knew full well what he was doing. Now; it could be argued that he was doing it to appeal to the Rangers fans, as opposed to winding up the Celtic fans. Only he can answer that.
