I wasn't going to keep playing but....
Ladies and gentleman, may I propose a hypothesis.
A spectrum exists in terms of the liking of small fry. At one end sits people that think all children are the epitome of wonderful, at the other are folks that literally hate them. Almost all of us occupy some part of the middle ground. Even people who have kids, if they are honest with themselves, would probably confess that they like their own more than other peoples, indicating that their capacity to 'like' children is also has a degree of variation to it.
Blade would seem to occupy a different position on this continuum than many of the rest of us, but, well, you get that. I am as wierded out by the need to associate over such a (for me) odd issue, it is by no means the oddest community out there in the wild and crazy web. That would be the folks who do exotic things to one another while dressed up in a variety of animal costumes. Fluffies, I believe?
Blade, the thing I think you are missing with the respect to the whole 'understanding' of parenting thing is the hard science that exists around bonding and the chemical changes that occur in the brain as a consequence of it. If you want I can go on a hunt and provide references, but suffice to say this is a well trodden piece of ground research wise. Simply put we are gentically designed to bond with kin, and as situations like adoption demonstrate, this set of responses can extend beyond pure kinship. Upon reflection, a better analogy than the sexual one that I used earlier would be taking hallucinagenic drugs. Yes you can understand everything in the world about things like neuro plasticity, but the experience of it will elude you.
