Actually India is a pretty good example for secularism. Yes, there have been religious violence a few times, but despite that India is still a country where people of every religion are equal in the eyes of the state/law, and have the same rights and freedoms.
You have to understand that there are hundreds of millions of hindus and hundreds of millions of muslims and tens of millions of other religions living in India. No other country has such a large religious diversity. Even in the west, you can see that as the muslim population has increased, there has been a lot of ill-will from both sides. There are anti-muslin rallies in Germany, muslims in France murdered cartoonists, and so on.
"Ghar wapasi" does not violate secularism. As long as the conversion is willing, it is not only permitted, but is a fundamental right. Anybody can convert to or from any religion. And anybody can peacefully persuade others to convert. The constitution states that all Indian citizens shall have the freedom to practice and profess their faith.
Gujarat 2002 was the last major religious violence we have had. Plenty of people have been punished for it, including a very senior minister in Modi's govt at the state.
