"Before Easter this year, Rachel Held Evans camped out for the weekend in a purple tent she had set up in her Tennessee yard. For nine days after this adventure, she abstained from sex and even from touching her husband. She stayed home from church, and toted around a stadium seat cushion to avoid sitting directly on chairs outside her home. Evans' goal was to obey the Bible's commandments for menstruating women in Leviticus Chapters 15 to 18, a passage that takes a lot of shalls and shall nots to make a simple point: Women on their periods are untouchable."
