That ongoing discussion about liquid that unintentionally comes out from fruit on Shabbat... Blood is also one of the liquids that can grant the food it comes in contact with (!) the capacity to become impure. R. Akiva is more stringent for the milk, over the blood. What do intentional and unintentional mean, in this context? What about other fruit (berries and pomegranates, for example)? And how do our expectations of what the fruit will be used for (to be squeezed for juice or not, for example) affect the bottom line psak? Again, the categories here are more than they appear to be, with more sub-descriptions and distinction. Note the focus on R. Menashye ben Menachem - is that too much emphasis on the practice of an individual, or is the halakhah that individualized? An example from the thorns in the fields - kilayim or not (well, are you in Arabia or not). The tension here is about a difference of opinion, a difference of practice, and an individual vs. the larger population. Plus: the statistics of it - and what point does the standard of practice change?
