IMO that dad is not setting a "loving" example. Love requires listening, compassion, understanding. I would say he is deforming his child's sense of morality. Hopefully that child has other examples to follow, and will at some point reach the conclusion that his father's crusade is not actually moral, but odiously self-righteous.

Nevertheless, trying to legislate for or against his vision of morality would certainly fail. Women should be free to choose (within reason), and he should be free to protest it (also within reason). This is how a true and resilient moral foundation for society can emerge.
