That would be called stealing, which i what men have done to us since the beginning of time.
The basis for it is men's fear that they are supporting and raising children that are not their spawn.  It is the basis of religion--control of female sexuality, like livestock.  It is still present in our own culture and others.  Men were physically stronger and were able to make slaves of women.  They stole our rights as human beings and want to continue to do so.  We weren't granted rights by men; it is just that some men knew that stealing our rights was very wrong.
