leg·is·la·tion (l j -sl sh n). n. 1. The act or process of legislating; lawmaking. 2. A proposed or enacted law or group of laws.
Legislation can fund a defense department. It can build roads, it can set up rules for business and trade.
It cannot change what marriage is. It can pass laws seeking a public acceptance of, and to legitimize, some relationships----but it isn't the legislature that ever formed the bond between a man and a woman. That institution way predates any government system or current religion.
It can protect the rights of parents. It can protect and respect life and human dignity.
Legislation cannot change when life begins. It can be warped and twisted for the sake of convenience, but a unique organism is a unique organism, and if a single celled anything was found by a Mars probe, everyone would be calling it 'life'...
Legislation cannot mandate prosperity. It can re-distribute, but legislated re-distribution is such a counterincentive to productivity, it overall brings prosperity down. Best to just stay out of the way.
Legislation cannot change the weather. It can impose carbon credits, punish corporations for being too successful, and remove a nation's competitive edge---but no amount of legislation will change the weather.
But they'll still try.
