Vampires dont actually exist, therefore you can't define them yourself, only your mear opinion based on what YOU know.
Oh, this response again.
I'll give you an easy to understand version:
You create a mythological creature, it's a white horse with a single horn, you call it a Unicorn.
They are known for being in touch with nature, drinking their blood makes you immortal, there's a few other things that make it a unique. You craeted this whole imaginary 'species', gave it details and gave it as awhole a name.
From now on when you hear of the term Unicorn it relates to those things specifically or rather the mythological species that contains those characteristics.
If I come out of nowhere and define a dragon with wings who has scales as hard as rock and call him a "Unicorn" I've 'stolen' the name and used it wrongly. It's terrible and is killing fantasy.
EDIT: Oh man I saw the rest of your post, OH MAN, OH MAN, response below:

I rather like this how new idea of a vampire and im glad its opening up different varients, instead of everyone having the same god damn opinion, people just refuse to accept other peoples ideas >_>
