Muhammad famously declared that "women are deficient in intelligence," NOT "Some women are deficient in intelligence, & some men are deficient in intel-ligence." As the testimony of every woman is worth half that of a man, he maligns all women:

Consider Marie Curie.  She won a Nobel Prize in Physics, and after her husband had died, a Nobel Prize in Chemistry.  Unlike Muhammad, she could of course read and write.  Our Debate Question:  Was she deficient in intelligence?

Is she "deficient in intelligence" & should her testimony be worth half that of a man?

Narrated Abu Said Al-Khudri
The Prophet said, "Isn't the witness of a woman equal to half of that of a man?" The women said, "Yes." He said, "This is because of the deficiency of a woman's mind."
