Should legislation include science and fact-less personal preference?
If the goal is to fight health risks there’s way to mitigate those risks scientifically in other ways that allows people to keep their preferences. Just saying “science” in a sentence doesn’t make your point scientifically valid, we don’t need to turn science into religion.
Or too take cigarettes example; ban cigarette sales completely instead of banning smoking indoors.
I hope you see the nuance now.
