Hugo de Jonge, a politician from Rotterdam, the Netherlands, has argued in favor of mandatory contraception for parents who are incapable of responsible parenthood. He will advocate for legislation on the matter. "Some children have the right not to be born," says de Jonge. The legislation would apply only to a select group of parents who are untreatable by other means. It is estimated that in Rotterdam, this would apply to 10 to 20 persons. He stated his plans in a speech at the start of a project in Rotterdam to convince vulnerable parents to take contraception voluntarily.
