But fear of rape has increased. — unenlightened
I agree. Lack of freedom of opportunity such as the ones you listed were evidence of the oppression of women up until the suffrage movement and the strides in equality since then. In fact I would argue that thing like pay rates aside, women enjoy the same opportunities that men do and in few cases now enjoy more opportunities then men.
However, I still don't see the correlation with rape.
Those who do commit the crime of rape have in the past used the reasoning that "they were asking for it" as defense for their crimes. As if by the woman's action, they removed the freedom of choice from the man. This is of course laughable as the freedom of choice is immutable regardless of the actions of others.
It is also true that sexual violence is on the rise, but here I propose a question. Is it on the rise, or has the definition of rape changed? For instance, have we included the act of touching another person's intimate body parts without their consent, generally known as criminal groping, as rape?
I would also dispute the idea that rape is normalized, down played, or laughed off. Excluding cases where wealth and privilege are factors, I don't think the middle class or lower class culture can fairly be charged with down playing or laughing off rape.
An example is the scenario of two adults who have intercourse after a night of heavy drinking. The woman wakes up and knows that she has slept with someone. The man may or may not be there. She may decide that she did not give her consent and accuse the man of rape. Both will agree that the act took place but one would argue it was non consensual and the other would argue that it was. Depending on the outcome of the case, a potential crime was played down, i.e. the man gets off lightly, or an innocent person is wrongfully imprisoned, i.e. the man goes to prison for a crime he did not commit.
Rather than work on removing a culture that among the average individual does not exist, it would be better to work on creating clear laws and procedures surrounding investigation of rape that protects both parties involved until a clear motive can be established.
