Comment Donating blood after a disaster (Score 2) 1718
"Posts directing people where and how to give blood have been removed."
While straight-up removal of such posts may not be the best approach, the intent behind such removals is likely honorable.
Donated blood needs to be screened for infectious diseases and otherwise processed before it can be used; it generally takes at least a couple of days before blood from a donor's arm can get to a patient's bedside. The blood that helps the victims of the Orlando massacre isn't the stuff that the Red Cross collects today and tomorrow; it's the blood that was donated last week or the week before. And blood has a limited shelf life--creating a big oversupply now doesn't help unless there's an enormous disaster in the next few weeks.
Donating blood now might make the donor feel good about themselves, but it's not actually a particularly constructive thing to do. If you want to help, put a reminder in your calendar to donate blood in two or three weeks, after this glut has made its way through the system. Or donate blood when the Red Cross (or whichever agency handles blood products in your jurisdiction) indicates a shortage. Better yet, get in the habit of donating blood regularly--help maintain a stable blood supply over the long term.
