The huge anti-James reaction post OotP seems quite characteristic of a certain part of the fandom IMO. I've seen a lot of very strange (well strange to me anyway) theories and heated arguments floating about that essentially revolve around the twin presumptions that a person's character is fully formed at 15 and that it simply isn't possible for a decent person to have done something in their youth of which they are not proud as an adult. My reaction to that? Bah, humbug.
