Buddhism has been criticized because it treats women as less than men. This mainly deals with women monks. Most schools of Buddhism have more rules for Bhikshuni (nuns) than bikshu (monks). Buddhists say that in the time of the Buddha, nuns had more problems like their safety. Monks often traveled in the forest and between cities. Because of this, more rules were created for nuns, for instance: nuns are not allowed to travel alone.
