Feminism assumes that differences between males and females in offending were due to the lack of opportunities in education and employment and that as more females were given such opportunities, they would come to resemble males in terms of offending

I believe the answer is: Liberal feminism

Offending in this situation refers to the act of causing a certain level of resentment toward a certain group of people.
This resentment often come from having to face discrimination/unequal standing. So, as females gained more opportunity like men in this context, the chances of females making the same offend toward others would also be increased.
