Should we treat all behaviors that are associated with a significantly increased mortality rate the same way, or should we pick and choose depending on the political and social context at the time, like we do with seatbelts?
This is my point: we pick and choose, and we're subject to the whims of society, when it comes to what we deem unacceptable. Citing a collective norm that potentially could have been influenced by societal ebbs and flows is not an objective argument, ever.
