The concept of marriage in a tradition-based society like India has a completely different meaning than "let's voluntarily have a contract, and we can break it off any time we feel like it."
In order to protect the sanctity of marriage (straight or gay, I support both), the government must resist calls to make it easy to divorce. Divorce must be a painful, punishing process if society is to continue to take marriage seriously. (It must nevertheless be possible for either party in the marriage to initiate a divorce to completion. That's non-negotiable.)
Just my view on this subject. And I accept that others with different experiences than mine may have different views.
