Sexual expression with a loving relationship is encouraged in Hinduism because it is not expression of lust, but expression of love and devotion to each others ' happiness.Threfore, is it not permissible that loving relationship( in other words marriage) , is also to be allowed?So homo sexuals should be allowed to marry.
In Baghavatam, , Brahma created group of demons that were obsessed with sex and demanded sex from him.But Brahma got freightened and ran away from them (chap 20, text 23, 24)
What about Hindu gods connected with gender diversity such as Ardhanateeswara, Aravan, Ayappa,cross dressing gods such as Bhavati Devi, Gadadhara,Gangsmma Devi ,Yellma Devi etc. etc
Why the system was promoted through rituals and festivals such as Aravan festival, Bhahucara matha festival of Gujarat, Yellamma Devi festy of Karnataka,
Though it is not officially recognised in Hinduism, it recognised those people, who showed signs of both sexes
Why, in Radha Krishna cult , is it not telling that only Krishna is man and everyone in the earth is a woman?
What about homo sexual iconography found in Hindu temples, carvings and paintings
Kama sutra vividly describes and covers this field.(preferably 8 & 9 chapters)
Rigveda says" Vikruthi Evam Prakriti" ( diversity is what nature all about) but stops short of elaborate description.
Homo sexuality is said to have existed since dawn of creation .There is no cut right condemnation of homo sexuality Hence it seems the sutras seem to support that homo sexuality was acceptable in ancient times also.
However it is a complex issue , as a human being they have right to exist and use their fundamental right which has been upheld in Supreme court of India
