India must implement a uniform civil code in order to reserve it's right to be called a secular nation. A uniform civil code is very important since it is the need of the hour to eradicate issues such as ''triple talaaq" which allows a Muslim man to divorce his wife by saying the word 'talaaq' thrice. Also, many christian couples have to wait for approximately two years in order to get a divorce as compared to any other Indian couple who can get divorced in less around 6 months to a year. Honestly, One nation One law is needed more than just a hashtag, but it is the symbol of national unity. Thus, to collate, I would just say that India must have a uniform civil code.
The caste system in India continues to make life unfair for people, especially in rural areas. A uniform civil code would ensure equal treatment across the board for all people of India regardless of caste, which is a step in the right direction toward not only equality, but eliminating poverty.
Universal civil codes seem to be the ideal set forth by the Western World, but, in reality, its simply a convention. Civil codes are essentially outgrowths of custom (vs. criminal codes which may or may not legislate against custom due to fundamental rights), and each state or town should be allowed its own code.
