you don't have a very good idea of what rape means.
rape means any form of sexual violation, including if you decide you want to have sex, but you're not ready and the man decides not to wait for you to get lubricated enough for it to be comfortable or even enjoyable when you ask. this is rape as well and it is just as traumatic. it is when one partner takes advantage of another partner no matter what the degree.
it doesn't matter why the women were treated that way. the fact that god's law does not create full rights and protections for women in it's original form demonstrates that it is flawed. god is perfect, his law is supposed to be as well. you claim god's law is perfect. his commands here demonstrate it is not.
