It's very sad that RBG has passed away. She accomplished a huge amount, broke barriers, persevered against all odds, was a proud Jew, I can go on. Baruch Dayyan ha-Emes.
Also, I feel the need to correct the following things:

1. Many sources in traditional Judaism do speak of Heaven and Hell. The normative traditional Jewish view is to believe in them. It is therefore certainly not offensive to invoke heaven in saying "RBG is on her way to Heaven" or something like that.

2. Saying "rest in peace" is not inherently offensive to Jews. (Note: וינוחו בשלום in Kel Malei *literally* *means* "rest in peace".)

3. To the extent that there may be some obscure source that those who die on Rosh Hashana (or the day before Rosh Hashana, which is when RBG actually passed away) are righteous-Tzaddikim, it is by no means a central or core or consensus idea. If it gives you comfort, good.

But don't blow whatever source you may have out of proportion. And please, *please*, don't misread sources to force Jewish tradition into some odd pseudo-paean to RBG.

RBG's passing is sad news. She was a remarkable woman. Our nation should mourn for her.
But please don't appropriate or misrepresent Judaism in your haste to concoct some Jewish-sounding tribute to her or pseudo-objection on its behalf.
Thanks!
