Live-in relationships tend to be viewed by Indian society as taboo. If any cohabitants are accused of being homosexual, they could be charged with a crime for not registering a live-in relationship. Under this live-in registration law, same-sex relationships are not permitted.
Conservatives despise gay people (and other vulnerable classes). They weaponize laws to harm these people. They are creating a weapon with this law and they will definitely use it as I am describing. While many may slip under the radar or not become a victim to this law, it is still designed to harm innocent people and teach the populace to discriminate against them.
