Old legends tell of vampires who avoid witches, as they are anathema to them. In other words, a true ancestral witch with powers passed from former generations is basically 'protected' (for lack of a better word) from a vampire's 'attack'. Conversely, lore also tells of vampires who attacked witches and were instantly debased and/or destroyed by the power of the witches’ blood.
From my understanding, witches and vampires have a general healthy respect for one another but rarely mingle due to the adverse affects, which might arise. Both these entities posses strong powers which are in diametric opposition to each other.
I am not speaking of 'nouveau' witches or vampires (in other words those who just title themselves as such with no proper understanding or - and this is very important, especially in the case of witches - any true genealogical basis and ancestral occult heritage.
It is all well and good that people are returning to the old religion, but frankly, most of those with the true power of leadership in that arena were obliterated by the mass extermination of suspected (and real) witches from the dictates of the church and their insidious inquisition and the fear that formed and held from the publication of the Malleus Maleficarum onwards. Being a new age witch and reading books does not a witch make. Neither does saying one is a vampire make one so.
Once that idiosyncrasy is deflated, then my answer would be - for those of you out there who would like to think of yourselves as a witch or a vampire but have absolutely nothing to back up that claim, sure - you can be both because your mind is in a delusional state in the first place.
If I offend, apologies, but I am Sith and call them like I see them.
