Joseph, I imagine that you would want to do everything you can to get people to respect Daas Torah. I’m sure you realize that one of the biggest problems with our generation is a lack of respect for Daas Torah, and that this is one of the areas that needs the greatest tikkun.
From things that you’ve written, I KNOW that this is a very important concept to you and one that you wish people would realize. So I don’t think you realize that when you post things like this, it decreases people’s respect for Daas Torah.
First of all, you don’t differentiate between Gedolim. The way you quote Rav Avigdor Miller, you make it sound like one must relate to his words the same way they relate to Rav Moshe Feinstein zatsal or Rav Shach Zatsal or even the Chofetz Chaim Zatsal. Rav Avigdor Miller was a tremendous Talmid Chacham but he does not belong in the same category as Rav Moshe Feinstein zts”l or the Chofetz Chaim zts”l, and no one is required to accept his opinions on divorce. When you quote him the way that you do, you make it sound like the fact that he said something makes it Daas Torah and something that everyone has to accept the way they have to accept things that the Chofetz Chaim said. If they can’t accept what Rav Avigdor Miller said, they will start to have doubts in the whole concept of Daas Torah and feel like they can debase the Gedolim.
In addition to the fact that Rav Avigdor Miller was not the Chafetz Chaim or Rav Shach, he did not necessarily mean to imply everything that you are attributing to him by quoting him the way you are. He did not say that most divorces are caused by incorrect conceptions of romance as you said that he did. Saying that most divorces could have been prevented is not the same as saying they were caused by wrong ideas of romance.
Furthermore, the statement that most divorces could have been prevented is a vague statement. All it means is that theoretically it could have been prevented if some things had been done differently at some point. This could mean that the divorce could have been prevented if the husband were willing to do something differently, but since he is not, the wife has no choice but to get divorced. It could mean that the divorce could have been prevented if the wife had not been exposed to certain things as a teenager, but now that she was, it is unavoidable. It could mean that the divorce could have been prevented if something had been done differently in Shana Rishona, but since it wasn’t, it is now unavoidable.
In any case, each divorce is its own situation, so it is not necessarily relevant what happened in another situation or in most situations. It is also possible that Rav Avigdor Miller dealt with certain types of situations. It is also possible that he is wrong.
