"I am exhausting my somewhat notoriously short supply of patience, so please excuse the following outburst:"
You said this paragraph from wikipedia seemed to imply that problems "arose after independence" and asked me to edit it.
Let us see what the paragraph says
"Since independence, India has faced challenges from religious violence, casteism, naxalism, terrorism and regional separatist insurgencies, especially in Jammu and Kashmir and Northeast India. Since the 1990s terrorist attacks have affected many Indian cities. India has unresolved territorial disputes with the People's Republic of China, which in 1962 escalated into the Sino-Indian War, and with Pakistan, which resulted in wars in 1947, 1965, 1971 and 1999. India is a founding member of the United Nations (as British India) and the Non-Aligned Movement. In 1974, India conducted an underground nuclear test[38] and five more tests in 1998, making India a nuclear state.[38] Beginning in 1991, significant economic reforms[39] have transformed India into one of the fastest-growing economies in the world, increasing its global clout.[20]"
Why should I edit this? Because it lists problems India faced after Independence?
I replied that such "problems arise" in every country after independence (implying that I don't feel the need to edit the paragraph) and I provided a example of how in another country "problems arose" after independence.
You didn't like that? Too bad.
To your original point about wikipedia I pointed you to a far more detailed wikipedia article (linked from the article you pointed to btw but then you didn't notice that) which detailed the history of India after Independence.
I don't see a need to "contribute" because you couldn't be bothered to read it.
(you aren't the only one with a short supply of patience and if you feel the compulsion to indulge in obscenity laden "outbursts" here, feel free)
