Do you really believe this? Based on what?
100% of the Pakistanis I've met (including those born in Pakistan) are extremely nice people and, in their thought processes, likes and dislikes, they are very similar to Indians. For whatever my opinion is worth, Indians aren't in the least petty, bloodthirsty, backstabbing etc. If you met them, I doubt you'd find 9 out of 10 of them so disagreeable, just like I find your countrymen impossible to dislike.
You said you were hopeful about India, what's changed? Modi's election? Newspaper reports about attacks on churches? Indians commenting on news websites and forums?
Out of every country I've lived in- the US, Spain, Egypt and India- India's mainstream discourse is actually the least jingoistic (even compared to Spain, at least the north of Spain!). The BJP's election is a correction of a historic imbalance where India was perpetually quite far left of centre. In any of the countries I've lived in the BJP would count as a moderate centre right party, a few loonies notwithstanding. Religiously divisive comments by politicians are far less accepted in India than in the US. Coming to Modi, despite some people's perception here of Modi being a mass murderer, India wouldn't have elected him if Indians believed he orchestrated or condoned the mass murder of Muslims.
A minor crime against a minority in India, even theft, is far more likely to lead to hysteria about anti-minoritism and the danger of the rampaging right than, at least, the countries I've lived in.
As for Indians online, you notice only a shrill minority, there are many Pakistanis on this forum that do your country discredit, but they aren't anything like the Pakistanis I've met. I lecture here (in Delhi) on my days off and all the kids I encounter are progressive fair-minded people. I'm not a nationalist and I'm only too happy to criticise India, but we're not a vicious, bloodthirsty people.
What has changed over the last 20 years is how Indians feel about Pakistan. There's a certain dislike or maybe disdain that's crept in towards Pakistan, even in the older generations. There's a view that Pakistan is a state without a conscience, willing to use any means at its disposal to get even with India for perceived wrongs and that it's imploding, consumed by its own hatred. The same people, like my grandparents, who would always cheer for Pakistan once India was knocked out of a cricket tournament will now cheer for whoever is up against Pakistan. This has only been strengthened over the last few years when the Western media has been telling us the same things about Pakistan as what our media always said. Few people have the time or the inclination to go deeper and realise that history is seldom about simple tales of right and wrong. This disdain, I agree, is an unfortunate development.
