Homosexuality versus Polygamy which is a sin and which is a human right? Why or why not?

Every society in this world has its culture, norms and tradition. There are various religion in this world, they are suppose to reshape peoples' behaviours because they tied to God to create phobias in them. Evidence are bound that Homosexualism was a crime against God and therefore a sin in the Bible. God destroyed Sodom and Gomorrah community of old and this is recorded in the Bible. If God said it is a sin why do man want to reverse his decision, is man playing God? I know individuals have their choices and rights but, it should be across the spectrum.   On the other hand, polygamism is a practice almost as old as the earth. They were popular and prominent people who remained classified today as polygamists in the Holy Bible. These include Abraham, Jacob, David and Solomon.  Societies who overtly and covertly kill an established and happy culture are human right violators. Furthermore the overlordship of one culture on another group/community/nation is suppression of the aforementioned, it should be deoxygenated in every facet of man coexistence. Laws of this nature should be deleted from societies across the globe. Human right calculation should be based on individual view of a culture and the side of the prism. Your thoughts!
