Does sexual liberalism lead to rebirth in the hungry ghost realm?
Let me present the so-called Tathagata Dhamma viewpoint, represented by Dhammadhatu. The answer is no, sexual liberalism doesn't lead to rebirth in the hungry ghost realm. You may want to want to read this answer to see why, according to this viewpoint, rebirth cannot fall into the dhamma of the Buddha. If there is no rebirth, then, logically speaking, there is no rebirth in the hungry ghost realm either.
