Firstly, the article is complete nonsense. You cannot take an abnormal situation (a fourteen year old bride . . . I mean, seriously?) and try to infer a principle from there.
Secondly, the whole piece about it being obligatory when both husband and wife don't want to that night. Totally false.
Thirdly, the laws of family purity are not meant to be convenient or easy. They force couples to connect in ways other that physical touch, and most couples who are committed to keeping the laws, discover the beauty in them.
Sure, they are difficult. They can create challenges. Children can also create challenges in marriage, but no one gives them up just because of that.
I think there is something for everyone to take away from the article.
One, it does help bring about the opportunity to discuss what the "average" religious person feels about the laws and how they can sometimes be inconvenient or not ideal etc etc.
And two what we can do to help those who are in situations where these laws are causing major problems in their yiddeshkeit and in their lives.
From my own personal discussions with friends, and many others I find that there are many people who really love all the laws, many who are just fine with the laws and see the good and bad and then those who it really causes major problems in their lives for whatever reason.
I'd say the majority of people I know fall into that middle group but that doesn't mean there aren't plenty of people who don't fall into the first or last.
And while it could be the average joe isn't struggling with these laws I'd say like many other areas as well there are enough who are for it to warrant a discussion.
