But by definition - as I said -
A Dhampir is when the child is born of a vampire and human through sexual manner (conceiving).
Where as for Blade, his mother was a prostitute who was pregnant when Deacon Frost feed off of her - passing the vampire enzymes/gene into her bloodline and into Blade (who was not yet born).
So he's technically not a Dhampir by definition.

So it's not a gross oversimplification. Blade is neither vampire, nor human, nor Dhampir.
Calling him a Dhampir is like calling Spider-Man a mutant, a dolphin a shark or a pizza a pasta.
