It wasn’t that long ago that people were celebrating the retrospective pardoning of gay men as old law was seen as an authoritarian intrusion into private matters. Now vast numbers of parents face being criminalised. The argument that it won’t be enforced is laughable. So why pass it? Passing laws that are not enforced undermines public respect for the law in general. For those who are hauled before the courts it will look more like arbitrary persecution more than prosecution.
