Darcy gives two reasons for refusing introduction to and dancing with Lizzy. One is that she is not handsome enough to tempt him and the second is she is unworthy of the compliment. If I insert one of the definitions from 5 into Darcy’s statement in place of the word “consequence” it reads exactly as Kathi explained it in her response to Jeremy.

Definition 5: "give (distinction) to young ladies who are slighted by other men."

Darcy is denigrating Lizzy’s situation in life or status if you will by claiming she is unworthy of the distinction which his partnering her certainly would give. He is sure of this because other men he feels superior to also chose not to partner Lizzy. As far as I can tell Darcy only implies Lizzy is not pretty enough for him and does not bother to ask why other men slight her. The fact that they do slight her is reason enough for him to follow suit. Mandy N is right when she points out Darcy was completely wrong in why Lizzy was sitting down and that he had no credible reason to slight her as he does. Darcy does not know much of anyone’s connections at the assembly but it does not stop him from snubbing them. He assumes from outward appearances that they are not worthy of his attention and Lizzy is just part of this unfashionable unattractive group of people. The unfairness of his slighting and insulting Lizzy is only worsened when I consider he does not know her or her background. His behavior results from blind unreasoned prejudice and as such is indefensible to me. ;D
