There's a lot of "Edward Cullen has spoiled me for real men! I'll never love anyone but Edward!" going around

This. Especially, this in re: cristalia's #2 above. I think the freakout is not so much a question of "are the impressionable kids going to see this worldview and adopt it?" as it is "Well, huh, the impressionable kids think Edward Cullen is the most fantastic-est thing ever; is that something we really want?" Not pre-emptive, but reactive.
