okay, i've seen this one post going around my dash a few times, and at this point i feel a need to say something about it:
vampires drinking from blood banks is NOT more ethical than drinking from live donors! in fact, it's worse!
most adult humans walking around on the street have a pint or so of blood they can spare with no real consequences for their health. (again, this is not true of everyone, so make sure you ask your donors about any health conditions before you get into it, but you were doing that already, right?)
but the blood in blood banks. the blood in blood banks is for people who need that blood in transfusion form to survive. blood shortages are real, and they kill. if you steal from a blood bank, someone could die for your theft.
the only reason that bagged blood is considered the "softer" option is because you don't have to look the people you're harming in the eyes to do it. coward.
