You miss understood me.“It isn’t a good fit for women” is being used to keep women from taking the courses, getting internships, getting published. It is totally not true. It isn’t be suggested as a liberal excuse. It is being told to women in high school and college as the reason they aren’t allowed to take hard physics courses. Being told to them as the reason why their schedules are changed to move them from the classes they want to take to other classes.
And if a woman does get into a real physics course and thrives there, she is encouraged to get internships and work experience outside of the field. Why? Because (and yes this excuse is still used): Men need those jobs more.
