NP: I think her primary issue is that one cannot use that Ramban to justify the position that Rashi holds that Yaacov is alive in the full physical sense.
I don’t know why you are putting words in her mouth that she clearly is NOT saying. She refuses to accept that according to the Ramban the passuk saying the Shevatim saw that Yaakov had died does not contradict Rashi’s statement that Yaakov did not die, as she keeps quoting that passuk as “proof” that Rashi CANNOT mean that Yaakov did not die.
How can you defend her citing that passuk as proof when the Ramban says it is not a proof?
