Neville:
I certainly did not mean to accuse, but I think the response is nonetheless on point.
I also find your hypothetical comparison in your latest post to be interesting, and well worth analyzing. And I agree that bias could play a role here.
Let’s examine the facts:
The NK member’s goal is correct and even vital, perhaps to the level of pikuach nefesh, but, in the final analysis, his particular methodology is incorrect.
Whereas the “RZ” are (as products of their education system, etc.) engaged in idolatry and heresy.
So:
If you remove all the labels and ask an objective Torah Jew which of the two is less Jewish, the answer is absolutely the “RZ” because he has destroyed, or at least severely damaged, his very IDENTITY as a (Torah) Jew. Whereas the NK could be (or is) misguided in these particular actions, but could otherwise be the same maamin as the greatest gadol.
The question, then, is: what “bias” would make someone call it the other way, to make kissing a murderer (done to hopefully save Jewish lives) to be far worse than idolatry and heresy?
