Sometime between when we were children and when we had children of our own, parenthood became a religion in America. As with many religions, complete unthinking devotion is required from its practitioners.
There are so many sweeping generalizations in this article that it's annoying more than informative, and tries to sway the reader in by using an inflammatory introduction. Try replacing the word "parenthood" with NASCAR fandom; Buddhism; veganism; alcoholism; it still works.
The article completely lost me when in paragraph 4 it makes a case that this started a phenomenon in the 1980s -- but by paragraph 8 it makes a laughable misogynistic statement about gender roles that would seem more apropos to before the 1940s.
If they're trying to say that parenthood is now a religion, what was it before? A cult? In the traditional sense of religion, people have different paths -- consider that there are Catholics, Lutherans, Jews, and many more -- all with different views about getting from point A to B -- and even what B is. There are classes of people that DON'T have the same path to raise their children from point A (childhood) to point B (adulthood); Not everyone is blinded to their children's faults, or is worried about persecution from the public because they publicly acknowledge their child had a dumbass moment.
The hardest part to accept about the article is that the characteristics of the 'parenthood' religion is what is described in this article, a single path, trying to implicate a norm and in their own way promoting what they are already criticizing for:
This is how a religion persecutes a heretic.
