I do, because it is an important point! Also I think you are confusing White Court Vamps with Red Court Vamps, while both are vampires, they are nothing alike.. WCVs appear human and in most ways are very human, RCVs are not.. RCVs can put on a human mask, and act human, but there is nothing human about them as we saw when Harry pushed Bianca with his sunshine hanky..
I think the WC are human, yes; humans with a separate entity inside them, the "hunger demon."
Some Whampires are more in control, others less-so. Mab says(implies?) that Thomas is human-enough to become a Knight, and Uriel seems to have a comparable level of interest in Whamps as he is in other Mortals.
RCV's are inhuman. They're like insects that have a parasite eat its way out of them, killing them. The half-turned Red is still human, but the full Rampire kills the host during birth.
None of which is to the point of the OP/topic: how much of the mind (memories, predilections, etc) of the human host remain with the full Rampire? Does the Ramp have the same "favorite color" as the human had? Do they remember what that favorite color was? Do they remember that "having a favorite color" is even a thing?
I will allege that
some level of memory remains; while I think they're born ravenously-hungry, Rampires are too capable of "pretending" to be human, too quickly thereafter. It appears
VERY much that there must be
some level of memory retained, or they wouldn't be able to "fake it" as well as they do.
