Catch yourself. I dont want to get caught up int he specifics of one example. bottom line is the gas case is muttar for any number of reasons, not least of which is pikuach nefesh.
I learnt in Ner Yisroel, when I last checked it was the second largest “black hat” yeshiva in america (Waterburry might be overtaking). There is no regular Halacha seder at least that is adhered too. I am not saying there should be, after all there isnt a chumash seder either, obviously that doent make it unimportant ch”v.
The bottom line is mainstream Yeshivas do not place a chashivis (or emphasis) on pactical halacha. I am not saying this is wrong or even a problem per se, but this is certainly the case.
What I do think is a problem, which is what i understood the OP as saying, is that as a result of the deemphasis of practical halacha, bekiyus, Nach and other limuddim, those who are not cut out for iyun are made to feel inadequate. Nobodody wants to feel inadaquate. Similarly those who are not cut out for learning at all, but have other kochos, be it music sports art etc are not appreciated for their strengths either. Obviously this does not mean Yeshivas should introduce Art, or music Sedorim. i am just pointing out a very real problem with no obvious solution or perhaps no solution at all.
