If this act starts getting misused on a large scale, the possibility of it being challenged in a court in India is quite high. Nowadays, in India, awareness among people is growing very fast and challenging a government policy in court is not very uncommon. Also, many NGOs are strongly raising the issues of human-right abuses and individuals freedom. To exemplify, RTI [http://www.rtiindia.org] can be cited as one of the big outcomes in recent days. Also, the Gujrat government is brought to its knees by a court for unfair treatment of minorities. There are many other examples too.

I can't say 'when', but, chances of it being challenged in some court is pretty high.

That's right. The idea itself is bad. You can comapare it with having something like idea of Jihad (actually the way the idea is being propagated by the hardliners, the bad way). If you have some unnatural/awkward ideas, you can have it happily within yourself. However, you should not be allowed to infect others with these ideas. Look it in this way: make some hate-speaches in a functional country (may be in USA also) and you will be locked up because you are infecting others with your bad ideas.

Gays harm a society in the same way cigarettes harm. It inspires others to try out something unnatural, which can't be justified. If gays want to have their own world INVISIBLE TO OTHERS, that's perfectly fine (on the grounds of their right to exercise their free will). However, as I said before, they should not be allowed to contaminate the rest of the world.

"Many US citizens still support oppressing the rights of gay people"

Just a different point of view:
Why do you exactly think that the gay-thing should be legalized or gays should be given equal rights what non-gays enjoy?! By all means, the gay phenomenon is unnatural and it doesn't seem reasonable to let a really small fraction of the population (gays) contaminate a society. You know, you can enjoy exercising your free will only if it doesn't harm others. If it does, it becomes an offence and it should not be given any legal backup.

I have said it before and I say it now: Wine is catching the mark.

Everybody, please take this opportunity to congratulate the Wine team!!
