Losing family is hard, believe me; I know firsthand as an older vampire. To defend the vampires that I've come to know in my time as a vampire, most people that we 'snack' on is mostly with the consent of the willingly participant. Yes, I will agree with you that there are those that have been killed from the feeding of one's blood...and that kinda has put a damper to what of the vampire old enough to understand what is right and wrong as far as our intentions are concerned.
If I heard the part of where Ms. Stackhouse, her brother, and a coven of vampires stationed in Dallas were trying to free Godric correctly, I believe you were forming a group that would have killed innocent people, vampire or not, on actions of just expressing themselves freely. Isn't that what the Constitution of the United States freely states? Freedom to express yourself without prejudice?
