Most of what is called “learning” is really nothing more than rote memory.
That is a gross misstatement. Did you ever hear the word “lomdus”?
Since learning Torah is not a mitzvah shehazman grama, why wouldn’t a woman be just as mechuyiv in it as a man?
You should look up the sugya in Kiddushin. The fact that women are p’turos from MAS”G is actually derived from Talmud Torah.
