Improvements in attitudes and some small improvements in women's actual position have made a difference. At least now rape is talked about and taken seriously. The overthrow of capitalism, and the end of the nuclear family as the only acceptable form of social organisation, will make a difference. However this will only be the beginning of the battle to gain full and absolute equality for women, which is the only way that rape will finally be dealt with. Attempting to reform people through coercion and force can never succeed.
Arguments based on fear and terror are never very convincing.
The institutionalised murder of the death penalty has never had the slightest effect on violent crime figures. It amounts to no more then revenge. Prison, if it achieves anything, tends to perpetuate crime with minor offenders often going on to commit greater crimes. Capitalism can not solve the problem. It creates the conditions which lead to most crimes.
