SlutWalks have taken place in some conservative Catholic countries such as Costa Rica, Nicaragua and Guatemala. According to "Sex and the Barrio" writers Edgerton and Sotirova, SlutWalk protests began in South America taking on the name "Marcha de las Putas". They are protesting the idea that women dressed in revealing clothing are asking to get raped. They held the walk in the South American capitol of Buenos Aires on 28 September 1990, a day that was named the Day for the Decriminalization of Abortion in Latin America. Due to the overwhelming Catholic influence, some SlutWalks have taken on an anti-Catholic tone in response to sermons, such as the one in Costa Rica, where a leading clergyman preached that "Women should dress modestly to avoid being 'objectified'", adding that the purpose of sex is "fertilization". The march even reached the Cathedral of San Jose just as mass was concluding.
