Back in the day when I was in high school, and had already decided that drinking wasn't for me, I still went to the field parties that we high schoolers had. I even provided a couple of 5 gallon coolers filled with fruit punch (I did not provide the PGA that was added). I did this for two reasons - my friends were at the party and I wanted to hang out with them, and I wanted to do whatever I could to keep them and others from leaving the party in a vehicle. Typically, we would all gather at a remote farm, have a bonfire, have music and drinks and the other shenanigans that teenagers in the country to. My friend Bob and I, usually the only ones abstaining from alcohol (Bob had lost his father when he killed himself, and thankfully no others, drunk driving) would collect keys from everybody and lock them in my truck. Generally, no one left until morning of the next day when they had slept off their drinking.
No, prohibition didn't work because the majority of the populace overwhelming loves to imbibe, and I can certainly live at peace in an alcohol-fueled world. Our area had always been "dry" since prohibition, but has recently voted to be "wet". I don't like it, I voted against it, but majority rules, so I'm okay with it - but I don't have to like it.
I applaud those, who I believe are the majority, that can handle their alcohol responsibly. I detest those who tell me that they drink beer for the taste; if that were true, O'Douls and Coors Cutter and others of the like would be much more prevalent. The reason people drink alcohol is because they enjoy the altered state of mind and body that is induced - and I'm fine with that - just don't pi$$ on me and tell me its raining.
I avoid alcohol (like 7 up - never had it, never will) because I believe I have a tendency to become addicted to things, and I am not going to gamble with that.
My children and I have regular discussions about alcohol and they know well how I feel. I will not condemn them if they choose to drink responsibly as adults, but neither shall I condone it, nor will I join them.
I don't expect to bring anybody over to my viewpoint, because I don't know how many times I see "...bring a case of beer over..." in terms of when people help neighbors and the like, and sometimes friends will "pay" you in beer for helping them move, etc. Beer/alcohol has permanently stained the fabric of our society and I think its a pity for all of those who have died because of it....
Good luck and take care.
