My view is:
Those of us outraged should lead by example. Let us all refrain from "social drinking". Even if it is once in a blue-moon
Make strict teetotalling "cool" again
It is healthy in small amounts.
It breaks ice in social gatherings...
One shouldn't "stand out" in a party where everyone is in the mood
It's not about how "responsible" you are.
It is about signalling!
This change has been engineered in the past 20-30 years
A similar cultural change can be brought about w.r.t. alcohol
