A lot of it here has to do with location.
In the Bible Belt, especially the buckle where I have lived most of my life, the majority of churches consider alcohol sinful (this pretty much kicked off during prohibition, when pastor Grape Juice decided to campaign against alcohol and wine in communion), strangely he had also "perfected" a new recipe of grape juice (you know him as Welch). After these crusades mainly by people such as Welch and "church women" who were fed up with their men being at taverns and pubs, many churches took very firm line stances against alcohol, going so far as to re-interpret the Bible and suggest that it is literal with everything except for wine. In which case, since they didn't have a word for grape juice (they did) when Jesus made wine, he actually made grape juice. They never stored wine, they stored the grapes in a non-fermented jelly solution then added water to it.
Ever since prohibition, virtually every independent and Southern Baptist Church have been completely against alcohol, to the point where consumption is sinful.
Presbyterians, Methodist, Lutheran, and Catholic are generally accepting of it. Most of the other denominations stand firm against it.
Religious people are easy to motivate to go on a crusade, if you can appeal to the emotional side of their moral compass. Just like marijuana and Reefer Madness. By showing something can be un-ethical, it is just blankly labeled as unethical.
In my opinion the Bible is about liberty through Christ. It is much easier to live a life of constraint with rules, however.
Bingo!
I live in Northern Louisiana and the town that I live in is very conservative! There was a porn shop that opened up here before I came to college and the town had it shut down quick fast and in a hurry. Not saying that was a good or bad move, but just showing that the town will not stand for certain things that a town 30 minutes away will allow. The town also has a law passed that no hard liquor can be bought or sold withing the city limits. Imagine my astonishment when I went to get my old man a 5th of Jack for Christmas and I couldn't buy it at the local Wal-Mart.
The bible belt is a funny thing. At my church, I make it well known that I drink. I do not get drunk, at all. I do enjoy alcohol on occasion. A beer with my burger, a drink with friends, etc... I started a bar band not long ago and made it very clear that my intent was to play the local club scene and if there was a problem with it I wanted to know now. Luckily our music minister is cool and said as long as I held myself accountable he had no problem with it.
