Walking between women has to do with kashe leshikcha. It causes a man to forget his learning could be it stam makes him forget even non learning things i remember seeing something like that but cant recall (I must have walked between women). Not sure about the others.
Tell this ljttle feminist in the making not to be so sensitive. Halacha isn’t arbitrary and everything has a reason and its all Hashems Torah. Tell her you can’t open a random chapter in Torah and start asking questions without knowing more information. Its like opening a chumash to where Hashem turns over Sedom and saying how can Hashem do that to 4 cities?! But if you look previously you would see why they were so punished and if you learn the medrashim you would see the extent of their wickedness. The kitzur is just that A KITZUR short version of the bare bones halacha. He just comes to tell you the basic Halacha. You want more you need to open up Gemaros mefarshim shulchin aruchs and what not.
