Statistics from across jurisdiction tell a grim tale about marriage, and even for young males, having any romantic relationships at all. In the UK, the majority of women between the ages of 16 and 34 have not married, and by then reproduction will be more difficult, compared to if it was done at a sensible age. According to Pew Research Center, 63 percent of US men between the ages of 18 and 29 are single. Then one needs to consider the failure rate of marriages, with 50 percent of US marriages ending in divorce, and for Australia, for example, the figure is less, at 41 percent.
So, clearly there is a problem. The feminist celebrates this, seeing heterosexual, but not non-binary marriages, as oppressive, patriarchial, blah, blah. But, marriage has been a foundation institution for society, and it is a bold experiment to see how far the fabric of human nature can be pushed. I predict disaster, then reconstruction from the ruins.
