That is just not the case. I'm not sure what has caused you to conclude that, but whatever has caused it, feminism is merely for such things as equal rights, such as equal pay or the same level job, and equal opportunities. It's not about emasculating males. If you've run into that it is the individual's personality and make up , not anything about feminsm.
I had a friend who had to go to a 3 year nursing school because her parents didn't think girls needed to go to college. She wanted to be an archeologist. So she went to 3 years of nursing school, then worked 5 years, and then went to college despite the fact that the 2 males running the archeology part of the museum told her there was absolutely no place in the field for females. ( as if troweling, shoveling, using a transit, taking notes, clearing brush off a site, making maps, is beyond a woman's capabilities.)
The women in the archeology department here at UF when I was in college, got a break because the archeology professor, Charles H. Fairbanks, supported the concept of women archeologists and encouraged some of us to go to graduate school, and our efforts there, instead of hindering them. I dropped out later, ( actually that was related to gender discrimination - I had several male housemates so I saw the difference in how our advisor ignored with me what he was doing for them finding and creating projects to choose for their masters thesis. , I just didn't have a name for it because I thought he liked me- a little too much in fact- I was just confused and didn't confront him because of the confusion about what it was and because I was raised to be passive and compliant- in other words a nice good girl and I still was into adulthood). Also, I can say the female colleagues I had who were academically brilliant and well suited for academia went through their PhDs, with this advisor obstructing them as a group way more vigorously and ongoingly than he did to our male colleagues. I was glad I dropped out before getting to that point. ( As an aside for those who know about the Annual Fairbanks Armadillo Roast- that was our group that started that on one of the birthday parties Dr. Fairbank's students always put together for him - he was much beloved because he cared way more about his students than how frequently he published.)
Anyway, there is a lot of misunderstanding about feminism. Women speaking up in groups had a lot to do with changing the approach to spouse and child abuse. Legally it was terrible. It was considered the family's business. It was like Tally with athletes only everywhere with non athletes. A routinely raped child under 13 or 15, I forget which, couldn't even testify in Georgia. The abuse had to have been witnessed. There literally was nowhere to go without a friend or relative to take you in, and no legal recourse really. A lot of you may not realize, but at one point in time in my adult life time, there was a little housing for men ( salvation army, ymca) but it didn't exist for women. The young people training programs were for men, not women. The teen girls looking to get training to leave bad homes or avoid a bad marriage choice had no options, and I know personally of one case which I now realize was almost certainly rape, where the parents wanted the girl , who got A's in school, to drop out of school and marry this guy 20 or so years older than her that she couldn't stand. She was desperate for options. There weren't any. Anything that did exist was for males only.
These things have changed some. It didn't change without help. Public awareness and education were key. And yes, somewhere in there, schools started having girls teams in sports as well.
