Just conservative? Isn't a defining feature of any government passing laws that enforce its way of thinking on others?

Yes, but when you have conservative governments, they try to enforce such notions. Then have an abysmally narrow minded point of view of the world and they try to make regressive changes to the country.

and no, the defining feature of any govt is not to enfore its way of thinking on others, it is to govern others in a proper way.

but at least in India, politics has become a business.

Not in any robust sense, no.
