In learning, maybe, in negatively judging those on the plane, the opposite.
Agreed to some extent, only because there may be a Mah Nafshach regarding either not flying or buying a second seat. Without an actual P’sak, it seems to be Soser itself Minei Ubei.
To clarify, I agree that they should not be judged negatively that they don’t want to sit next to a woman, but rather that they did not realize this may come up and buy a second seat for this purpose (similar to someone overweight buying a second seat on a plane due to their considerations. Eizehu Chacham HaRoeh Es Hanolad). This is even more so if there was a P’sak (as as such, this was thought through beforehand).
And Takah, I also have a non-clarity on the P’sak Rav Vosner as well. Why would the Yarei Shomayim in question not be Mechuyav to take a cab, as then there would be no Shailah of Histaklus or Negiyah? The Shailah presumes that there are forced to travel the bus (second line), but why is that true?
