I never really gave it much thought as to libertarians and feminists motivations since their arguments are so flawed at times, I tend to dismiss a lot of what is said. But you make a good point on how they value freedom, freedom above all and freedom at all costs.

Freedom really only has value if you place value in it, if you want to make your own decisions and enjoy that you will also have to take the brunt of your poor decision making too. People don't want to take that risk and only want the idealistic form of freedom that suits them when it's convenient but they happy to give it up when it's not. If you valued freedom, for example, why would you give it up to use something like Facebook. You would rather have the benefits of access to mass communication than the freedom and privacy.

I feel true freedom cannot exist without rules. We need rules because freedom without rules means you become a slave to your own desires and that really isn't freedom at all!
