Aveira,
We know from the Gemara in Yoma and Medrash Shir Hashirim that those who ignored the Nevi’im and stayed in Bavel during Bayis Sheni prevented it from becoming the final Beis Hamikdash.
Our redemption is held back by frum Jews who should know better constantly spewing criticism and hatred against other Jews and even worse, entire groups of Jews.
