Care to explain?? I personally only believe in information that is held as credible by the mainstream majority and backed by substantial evidence (eye witness accounts, recorded transcripts etc) but I realise what's credible for Indians and the West may not be credible for others. As far as I can see, there is no evidence, not even provided by those putting forward such CTs, to support some of the ideas banded around in Pakistan (unless you know something I don`t)..
What you believe is not the point. It is what is believed by Indians in general. There is no evidence to support a lot of things that Indians openly believe about Pakistan or ISI.
Now as far as mainstream majority is concerned,
1. Which mainstream majority outside India believes this? I can guarantee you these theories are not that popular in the west contrary to what you believe.
2. It is still irrelevant whether many people believe it, since that just means that the conspiracy theory is more popular. It is still a conspiracy theory nonetheless. Just because more people believe in your conspiracy theory, doesn't make it any less a conspiracy theory. Please get out of this mindset and using argumentum ad populum as your form of argument. You are in no better position than you suggest others are.
Every govt engages in propoganda and misinformation and although people can occasionally get whipped up into a state of frenzy I don`t see any enduring mass hysteria about the 'foreign hand' gripping India nor have I encountered the visceral hate and racist beliefs, at least among my relations or those I meet during my visits to India, for muslims or other communities that many posters on here appear to harbour against Hindus/Jews/West. I believe it is this fundamental pattern of idolising "us" whilst on the other hand denigrating the 'other' and the tendency to project unpleasent emotions and "evil" on to others that makes certain societies especially vulnerable to such subvesive ideas.
ISI conspiracy theories are quite popular in India, similar to RAW/CIA/Mossad in Pakistan.
What gets lost amidst all this is the ability to self reflect and recognising one's own short comings, which could then lead to lasting peace and reconciliation. The powers that be have a vested interest in keep society in this paranoid schizoid state of thinking as it let individuals avoid having to face up to their own failures, as a convenient "evil" enemy is always at hand to shoulder the blame.
Again, goes both ways.
