To be more specific, there’s a strain of white Christian nationalists that believe the book of Revelation predicts that Jews will rebuild a third temple on the Temple Mount site and resume animal sacrifice before the rapture or any other end-of-days event can occur.

To these people, activities that make that outcome more likely are laudable expressions of faith. There’s even a group that is trying to breed a perfectly red heifer in Texas, because apparently you need to sacrifice a perfectly ritually “clean” and unblemished red heifer in order to properly kick off a new temple.
