"California is officially the first state that will try to require companies like Apple, Facebook and Alphabet to add more women to their boards"

"The More Gender Equality, the Fewer Women in STEM"

so it all boils down to this; stem fields are mostly occupied by men (usuall more than 70%), so if tech companies try to hire more than 30% women among their employees, they're probably preventing a lot of competent men from entering the job market. and this is discrimination.

but FEMINISTs would ignore these facts and argue that half of employees must be women and thus push great companies like apple to hire more women.
