Neville, I am Chassidish. As I said, after arguing here for some time I asked a well learnt person if he thinks Yaacov lo mes means that Yaacov is still physically alive. Well, that person is Chassidish and looks like he learnt the meaning of what Rashi is saying differently than you.
You keep on repeating over and over again about “rejecting Rashi or laughing at the Rashi”. That is simply ridiculous. Just because you interpret the Rashi (or was taught to interpret it) to mean that Yaacov’s body is physically alive (and Rashi does not explicitly say that) does not mean that others who were taught differently are “rejecting Rashi or laughing at Rashi”.
