“There are only 14 million Jews in the world so I am not sure how you can have millions of divorces And intermarriage is only a problem for Reform & Conservative Jews not the frum community.”
Regarding intermarriage, he didn’t actually say that he was talking about Frum Jews. And intermarriage actually is a problem in the Orthodox community as well although in far, far fewer numbers. But to the extent that it does exist in the Orthodox community, I would imagine that internet may play a big role.
And regarding divorces, he didn’t say that he was only talking about Jews (when he said that internet caused millions of divorces).
