In the recent times, in India it's a fashion to support LGBT (Lesbian Gay Bi-sexual Transgender or non-straights). Most of the people (including Gnani, whom I don't agree on this topic) write that it's been recognized as normal scientifically, legally, etc. But, the fact is that Science keep changing--one person proposes one theory and the other disproves.
Whoever has seen the transgender's dress lifting trauma can clearly understand that it's more of mental thing. It also worth to mention that LGBT had successfully been treated with mental therapy. But, the Indian blinded mob is now attacking Ghulam Nabi Azad for his remark on homosexuality. I strongly agree with him though I think, his western remark is unwarranted (Transgenders are been in India for decades).
