NinjaDork: What books do you read / video games do you play where sorcerers/esses are regularly portrayed as jackasses? Because I'm finding it difficult to understand how you got that impression.
Hickory: Clearly not well read. How about, for starters, Morgan le Fay, Circe, Voldemort, Sauron, Vigo the Carpathian, Randall Flagg. Not to mention Yennefer of Vengerberg and Philippa Eilhart. There's many, many more, but you'll just have to take my word for it... or look them up.
Morgan le Fay, Circe, Voldemort, Sauron, Randall Flag, and Yennefer I recognized right off the bat. However, my experience with the "sorcerer/ess" type has leaned more heavily towards folks like Polgara the Sorceress, Gabrielle Belisarius, Inquisitor Ligeia, Professor Mcgonagall, Honor Harrington (she's a bit of a stretch, but between her gene mods and her over-the-series development of psychic powers, I stuck her in there), Skeeve and Aahz, Skandranon and Darkwind and Elspeth, and a bunch of others that I'll leave unmentioned for now.
Also, you started your involvement in this thread by being a bit of a jerk, and you've been slowly-but-consistently scaling up to full jackassery. I haven't been very polite myself, but I'm beginning to wonder if you have some obscure personal grudge that you haven't bothered to mention.
EDIT; Forgot to mention Gandalf-as close to a direct opposite of Sauron
in the same series as we get.
