The Gra is quoted by his talmid Rabbi Hillel Rivlin (“Kol HaTor”) as sayingthat just before Mashiach comes this sin will infect those who hold on to the Troah. Rav Teichtal says (“Em haBanim Semeicha”) that opposition to our return to EY is this sin.
So basically, you have so much emunas chachamim that if the talmid of the gra said it will happen several hundred years ago, then it must be what is happening now.
Very nice.
Today’s chachamim disagree. How about some emunas chachamim on dem apples?
