This has nothing to do with 'not being able to go a day without alcohol'. It's down to the fact that wine is, and has been for literally thousands of years, a civilised (not drunken hedonistic) part of having a multi-course celebratory meal. If you need to have a beer with your pretzel every time, fair enough. But this isn't the case.
America has probably the most backward views about alcohol outside of the Muslim world. It really is ridiculous that wine and beer with a meal can be considered an attack on family values and don't even get me started on the fact that the drinking age is 21. In Europe alcohol is seen as a part of life and children are brought up to respect good quality products. It's is not unusual for children under 10 to be given a watered down glass of wine with a meal at home. It is respected because hundreds of years of work has gone into producing excellent quality produce to enhance the taste and dining experience. Not to get wasted and vomit on the teacups.
Those against this need to really see the difference between alcohol for getting drunk, and alcohol to enhance a dining experience. Family values aren't just preserved for the teetotal, white Christian traditional parenting families. They come in all shapes and sizes. The world would be a far nicer and inclusive place if people realised this.
