It is true that marriages with same Gotra should not be encouraged. At some times if such marrige can not be avoided the bride is usually adopted by a person with other Gotra and marriage is performed. But this is of no use as genes can not be changed by juust adoption.Scientifically it has been proved beyond doubt that such marriages must be avoided. As stated by a blogger Muslims marry father's brother's daughter and very close relatives which is not acceptable in Hindus. Therefore, deformities in Muslims are considered to be high as stated. The Egyptians married their own sisters. Cleopatra's case can be quoted. The entire race vanisihed. Gay culture is a different story and no civilization and society has been free from it. some openly practiced while others enjoyed behind closed doors.Muslim chieftains and kings had scores of Hizras in their palaces. They were protecting harems and were used for perverted sex activities. Any how , open gay culture is not Indian culture. In fact it must be opposed. This has to be discussed at length separately
