Ron was also a racist for a good portion of the series.
Ironbite-what? It's true.
At least
that is halfway understandable since almost all of his society is racist, product of his environment and all that. What I find most annoying about him is that he never, ONCE shows any signs of gaining any maturity. Hermione and, to a somewhat lesser extent, Harry both actually bother with growing up thru the course of the series; Ron seems to be perpetually stuck at around 13 years-old or so. On a quest with your friends to find and kill the phylacteries of Liche Hitler? Clearly, you should storm off in a huff and leave them behind enemy lines to fend for themselves. Ron's the kind of guy that wears weed leaf T-shirts into their 30s and never moves out of his mother's basement.
Also, would Voldemort count as a liche? I mean, he was technically killed when his curse backfired on him, he has at least one phylactery that guards part of his soul, so it really comes down to whether or not he counts as undead...
