Genetic counselling exists, where parents can get information about their heredity and even prevent the birth of a child if it has a risk of hereditary illness. Some people do not think the issue is so clear, though, and wonder if genetic screening, genetic counselling, and birth control, are all just another type of eugenics. Some people wonder if it is bad because it infringes human dignity. Some people oppose eugenics and genetic counselling for religious reasons. The idea of eugenics is controversial today for these reasons.
