The strong taboos against homosexuality, bestiality, and transvestite that exist in many societies which are result of attempts to establish and defend strong ethnic, religious, and the boundaries among groups. If their own group leaders decide to strengthen the boundaries of their group, they tend in consequence to impose penalties which are even harsh on forms of sexual behavior that breach social boundaries. This may be because they have adopted a code of belief and conduct that emphasizes the need to maintain boundaries of all kinds, including those between humans and animals and between males and females. They also wish to prohibit the formation of sexual relationships that cut across the internal and external boundaries of their group or organization.It is also common among the human inbetween the individual.On treating equal eachother makes it an equality!!
