We know that women students and staff remain underrepresented in Higher Education STEM disciplines. Even in subjects where equivalent numbers of men and women participate, however, many women are still disadvantaged by everyday sexism. Our recent research found that women who study STEM subjects at undergraduate level in England were up to twice as likely as non-STEM students to have experienced sexism. The main perpetrators of this sexism were not university staff, however, but were men STEM degree students.
So you first said they try to do/offer to do something like walk you home, buy you something, etc. and you said you don’t want that. Now here you say you want them to do something, in particular when they see something bad happening (i think you meant when they see girl treated poorly by a boy/man). That seems kind of confusing.
