Wow, after reading your profile page, a few questions come to mind:
Do you ever get outside? Do you ever take a deep breath and go for a nice walk around the block?
Get some sun, man. It'll be good for you.
Also, as you note ... obsessive. But love is obsessive, and to my view obsession is a great ability to have if applied correctly. It is an awesome ability really, and a needed one in society.
To a classifier, such a magnificent one, things must be "just so" to work! And that is one reason many of the fiercest Darwinists are obsessive, catholic (arreligious sense of that word), classifiers with personas that demand not only only must things be classed "just so" , and order be made of the universe, but also that words, their meanings, be exactly *this* (that is the *this* of exacting specificity in each case) exactly fitting the classified order their psyche needs imposed on the world and all its contexts and observations.
Note that such a minded persona, such uniquely abled individuals are found in great number in fields that thrive on classification. This in Science, biology is rife with them, both in professional and non-professional standing.
There is in biology, of course, classification systems that are alternate to Darwinism's. Cladistics, and historical classification systems that predate Charles Darwin. Yet in none of those is the act of classification itself such an necessary and intimate dynamic of the system. Darwinism is built, almost in whole, on deft classifications. AND on strict and restricted definitions of terms. All to the Order of Things, you know.
That obsessiveness -- what a magnificent and blessed thing it can be! -- goes hand-and-hand (that is, is a very closely affine trait) with (1) a certain limit on reading comprehension skills, that being a limitation on the ability to see alternative and read subtle, non-direct, contexts out of material, and (2) as posting history demonstrates an obvious limit on the ability to understand the arguments of their intellectual opponents, to make the most sense possible out of expressed disagreements, which results in a limited ability to respond converstaionally. fairly or even politely, and in a too quick resort to energetic name calling, mockery, and slander.
LOLOLOLOL!!
For a newbie, that post was precious. But, be fairly warned. These folks take to the evolutionary paradigm very, very seriously.
A lot is at stake for them you know.
