Yeah, that seems to be an unfortunate thing about HP fandom whatever the subject, that people get into this extreme thing where a family is either loving/good or has problems/bad. I just really don't think JKR naturally writes too many relationships that don't include some abuse of power. I was recently reading somebody somewhere making a comment about how she calls Snape a "bully" and so that's a criticism, which it is, but it just never fails to amaze me how "bully" is the central idea of everything in the books. You're either a bully, a victim, or a protector from bullies. The second group grow into either one or the other, and the first and last are sometimes indistinguishable. It's no wonder the ideas of Slinkhard (the author of Umbridge's textbook) is presented in such a strange way in canon, imo.

I loved Regulus since we just heard about him in OotP, but oh, he and Sirius are becoming more and more interesting to me. I'd love to hear their story. I think we might hear more of it in the last book. Regulus is ready to shine there.
