Tronic, not everyone has the knowledge or inclination to argue the way you are suggesting. Personally I am not religious, I have a liberal POV, and my arguments will be liberal. And as you said, liberal arguments don't work with them.
Banglorean, the problem with most Indians here (not you) is that they pretend to argue from a liberal POV but in reality it is anything but. For example, go take one look at the cow slaughter and beef eating thread and the same people who beat their chests at banning cow slaughter come here and pretend to be all liberal and take jabs at Islam. That's a bloody joke.
I was talking about the "victimization stuff" that many of my old Muslim college-mates have begun posting on facebook. It was just an observation about the changes that have happened in them, and a worrying observation IMO. Not all of us can implement your suggestion to debate and argue them out of it. All the more so on Facebook, where many of us have people from professional life, and people of different nationalities, different religions in our friends lists.
Well, I agree with you that it is awkward, but the only reason it is so is because as I said before, India is a very segregated country. You can only talk to people on those topics if you are close to them. I try to keep politics off facebook too, but I will casually bring it up on msn, or when in person, and tell them why I think they are wrong. Indians on the other hand are a segregated community, and we grow up raised on biased propaganda. The "cunning Baniya", "khatar Musalman", "SC/ST quotay wala", and all types of BS biases are fed to children in India as they are growing up no matter how much you deny it. That's the one reason you have this much backbiting and groupism rather than putting forward these exact same opinions on a one-to-one personal level.
