ZD: You’re ignoring the reality by saying this psak will “turn people off.” Non-religious people are not going to differentiate between us “discriminating” against black Jews and Black goyim with regards to wine production; they’re just going to consider this entire halachah racist. Also, we don’t posken based off of what turns people off. What’s probably going to happen here is that massive pressure will build against the Badatz, and they won’t crack because they truly don’t care what anyone thinks; they just care about the correct halachah. The Rabbanut, on the other hand, would and has cracked in the face of PC pressure. Hence why many Chareidim respect the Badatz more.
I don’t think the situation will affect “all Ashkenazim” as asserted above. Not many American Ashkenazim insist on a Badatz hechsher, and it seems like it’s keeping its other respectable, non-Rabbanut hechshers.
