The very popular and recent case is the case of Ilavarasan and Divya. The girl belongs to an upper class and the guy belongs to a lower caste. Their relationship was not approved because the guy belongs to a lower caste. They got married and fought in court against the opposition group (the family members and community
members). But the opposition overpowered them and they both were separated. And on one dreadful day, Ilavarasan was found dead near the railway track. The upper caste couldn't tolerate the idea of their daughter marrying a person from lower caste because it's polluting the caste and community.
The zero tolerance against inter-caste marriages and other caste issues destroy our unity. Those who fight for their caste doesn't know the meaning of unity in diversity because they want unity only in their community, they fail to understand the larger picture that is India. By concentrating only on their community, they destroy the peace of India.
Unity is the main aspect which should be present in a country. If unity is destroyed the whole country will be in ruins. We are different in many ways but understanding the differences and coming together is the only way to destroy the evils of our society which ruin our peace.
It's easy to read and write about unity but practicing it in our day-to-day life is very difficult. Let's make the impossible, possible and show the other nations what unity in diversity really means.
