sighs I really shouldn't write so much when I'm half awake... Just wanted to clarify and expand on one of my points now that I'm completely awake:
"-How skewed is the population problem? Is the polygamy solution just something Harry and his friends are doing, or is it something that pretty much everyone is doing?"
Basically what I meant by this is to ask if it's something that is only occuring in Harry's age group (however old that might be), or is it also occuring in other age groups? For example, assuming that this is set several years after Harry's graduation, what's the situation like for the years below him? Are they just as skewed, or are they closer to normal? What about the older age-groups, given that as far as I can remember, the Death eaters were generally male?
