Throughout the Vampire Community you will notice that some people use the term Mundane .
I've always had an issue with this term being used. Why can't someone just be called non-vampiric? 
It is my opinion that no one is truly mundane. One of the definitions of mundane is common; ordinary; banal; unimaginative.
A lot of people I have found do not like this term either. They find it very derogatory. When I think of the term "Mundane" I think of things like this: doing dishes every day, is mundane.  Or doing laundry is mundane. But people being mundane, never. All of us have something that makes us special or different than everyone else out there.  Donors are definitely not mundane, if it wasn't for donors, many vampires would become quite ill. Donors or very important to vampires, so I really don't see the reason to call them such a derogatory term. And those who are not vampiric, are they any less special? What about the occult/witchcraft community? They work with energy, are they mundane as well? In my opinion no. Even someone who is not aware of energy, in my opinion is definitely not Mundane. We all have some kind of imagination and according to one definition of mundane, it means unimaginative. So why use the term to describe another human being?

What's your opinion on the term Mundane and it's use in the Vampire Community?

I personally, hate the term mundane as well.  I am not a vampire, and I am nothing near mundane.  I agree with you, Mel, that no one is mundane.  I find the term highly derogatory and unnecessary.  My boyfriend is a vampire and I am not, and in a lot of cases, he's more "mundane" than I am.  Lol.  Anyways, I'm glad ADN and DE doesn't really allow the use of the word "mundane", and I stay away from sites which do.

I also agree with bobby, that its just a way for vampires to feel like they're on a higher level than everyone else.  It makes one feel special to be better than those "mundanes".

People get way too caught up in the romanticism of the classical/fictional vampire, and don't realize the actual condition for what it is it seems.  They just try to elevate themselves above others, which is completely ridiculous and self delusional. Those people are the ones who really bother me.

I think it can be used to describe humans or non vampiric/non otherkin beings. It's really just a matter of preference. But when I use it , generally I would be speaking in the manner of the above written text.

True. I think that some use it as a way of trying to distinguish those that are spiritually inclined and those that are not. But that's not what the definition of the word is...
