According to this story, Satanists are hoping to challenge anti-abortion laws on religious grounds. Via RawStory: In a statement, the Satanic Temple said that it will use the Supreme Court's recent Hobby Lobby decision to exempt its believers from state-mandated informed consent laws that require women considering abortions to read pro-life material.
Informed consent or "right to know" laws state that women seeking elective abortions be provided with information about alternatives to the procedure, often couched in language that attempts to personify the fetus. According to the Guttmacher Institute, 35 states currently have informed consent laws, and of those, 33 require that the woman be told the gestational age of the fetus.
