THE ABUSE AND SATANIC RITUAL ABUSE OF CHILDREN, AND HUMAN SACRIFICE CEREMONIES IN GENERAL
To hold their human form, these entities need to drink human (mammalian) blood and access the energy it contains to maintain their DNA codes in their "human" expression. If they don't, they manifest their reptilian codes and we would all see what they really look like. "Oh, my God, Mr. President, do you always eat your breakfast from across the room?".
From what I understand from former "insiders", the blood (energy) of babies and small children is the most effective for this, as are blond-haired, blue-eyed people. Hence these are the ones overwhelmingly used in sacrifice, as are red- haired people also, it appears.
