Sister-fucking is the new frontier of the sexual liberation movement. In the last decade great strides have been made in the west when it comes to the removal of sexual taboos with feminism, lgbtq+, and the removal of stigmas associated with sexual fetishes like zoophilia, furryism, pedophilia, bdsm, necrophilia etc. The familly unit however remains a prudish and totalitarian relic of the victorian era. There is no reason for the family to remain intact in it's current form within the current progressive paradigm and the social taboos associated from familial-sexual relationships must be removed. There is literally no reason for a brother and sister to not be in a lifelong sexual poly-amorous or even monogamous relationship from a young age. There is no reason for children to not sexually experiment with their parents and siblings since they are their closest and most trusted kin. The social taboo associated with incest has no reason to exist outside of reactionary and outdated religious dogmas.
