Today I saw this question: History of Birkas haMinim, which got me thinking: Nowadays, that we don't have Tzdokim or little Judaic Temple-cults like the Essenes, whom is the Birkat Haminim directed at? Just Christians? Or other religions? If the latter, then: all other religions or just some of them? And might it also be directed at some Jews (Chalilah?) as it was in the beginning? What about Kara'im and Shomronim?
