Hundreds of "satanists" attend the Satanic Temple's SatanCon, a three-day event in Boston that includes presentations and discussion panels. The organization describes itself as "dedicated to the practice and promotion of individual rights." "So we don't believe in a literal Satan. Satan is a literary metaphor. And, you know, surrounding that we have our seven tenets, which are the basic tenets of empathy, compassion, justice, bodily autonomy, things like that all together to encompass our general philosophy of life," says Chalice Blythe, one of the organizers of the event. Religious protesters opposed to the event gathered outside the venue. IMAGES AND SOUNDBITES
