People are free to do as they choose, form groups as they choose, and oppress others as they choose. There exist no governments. There exist no laws. There merely exist big groups of people who like to try to force their beliefs and values upon those who don't conform to them. This is permissible, however, because we live in anarchy.
People are free to kill and rape.
This is all permissible, for we live in anarchy. Two people are free to have consensual intercourse. Of course, this is all permissible. We live in anarchy. Needless to say, anything's fair game in anarchy.
