I happen to be a non drinker just not for me. Strange I know so it is not an issue.
IMO drinking does not mix well with weapons,Motorcycles ,cars, ATV's and watercraft.
The world has just gotten to crowed. There was a time it was not as big a deal as it can be today.
I am sure most shooting do not happen over a friend having a beer on the way home but there must be a line somewhere.
