Ubiquitin: “Joseph said “We all should hope that we, like Rabi Akiva wished for himself, when our time to leave this world arrives we should be killed al kiddush Hashem.””
Ubiquitin, Joseph didn’t say that we should daven to die the exact way that R’ Akiva did, only that we should daven to die al kiddush Hashem just like R’ Akiva davened to die al kiddush Hashem.
If you think that it’s possible to die al kiddush Hashem w/o a misah meshuna (which I personally have trouble seeing), then this argument (that we daven not to have a misah meshuna) is not a good argument, since the argument is about whether or not we should daven to die al kiddush Hashem.
