Gavra-at-work: “Where is the Aveirah of voting for Meretz? Does this tie into “following the Gedolim”? Wouldn’t that be an additional qualification?”
I think it would be “not following the Gedolim” which is part of being Shomer Torah and Mitzvos.
I was almost hoping you would go there.
1: Following the “Gedolim” is an absolute qualification for being a Chareidi.
2: Included in “following the Gedolim” is voting Gimmel, as the Gedolim have told us that we must vote Gimmel.
Hence
3: Anyone who did not vote Gimmel is not a Chareidi.
Or
3: One may have different Gedolim than you (ex. Satmar Rov, Rav Avital, Rav Meir Stern, Rav Fuerst, etc. etc.) and still be a Chareidi. If their Gadol doesn’t tell them for whom to vote, they may vote Meretz (or Labor, NRP, etc.).
This assumes that having the Gedolim tell people from whom to vote is not a new “movement”. Gantz Shayach it is, as ubiquitin said earlier.
