Alcohol is an interesting substance. Its use is another controversial topic from a Christian perspective. Similar to sexual issues, it is addressed directly in the Bible, but many aspects are open to interpretation. Abusing alcohol, by drinking too much or too frequently is explicitly prohibited. But some Christians have erected other "fences" around the issue, using those limits to justify outlawing all consumption of alcohol. While that may be an acceptable outcome, doing something for the wrong reasons will eventually lead to problems.
Jesus’ first recorded miracle as to turn water into wine. Jesus shared wine at the last supper, presumably red wine since it represented his blood. Paul advises Timothy to drink wine instead of water exclusively. So clearly the Bible does not completely prohibit the consumption of alcohol.
There are lots of potential negative consequences of drinking alcohol, especially as usage increases. It impedes one's judgment, and relaxes their control over their actions. This could encourage someone to do something we will later regret, especially if it is something they would not normally have otherwise done. In this modern age, drunk driving also endangers the lives of innocent bystanders.
So I don't think there is anything wrong with taking a stand against drinking, and even encouraging others to abstain as well, but doing so based on the idea that it is prohibited in the Bible is the wrong approach. If you are going to completely abstain from alcohol, do it because of the natural consequences as opposed to because God doesn't want us to drink, as if there is some intrinsic evil property to alcohol. Now God may not want a certain individual to drink, as in the case of a Nazarite, (see Samson-Judges 13) but that is a case for select individuals, and should not be used to govern the general population.
I have a much more impartial perspective on this topic than on the sexual one, because I have no personal interest or struggle with this issue. I don't even like drinking, so I am not necessarily bothered by that option being taken away, but I also don't like seeing people deceived about the nature of God, and what he says.
I drink very rarely, not because I think it is wrong, but because I don't particularly enjoy it. I don't usually like the taste, and between having a high metabolism, and a strong stomach, alcohol has very little effect on me. I have had people in college try to get me drunk, and I played along, out of curiosity I guess, but never felt any different from the experience. The best they could say was that after a lot to drink, I seemed a little more relaxed. But it never really appealed to me in the slightest, so I only do it once or twice a year, when the situation calls for it in the name of being polite. (My brother on the other hand joined a fraternity in college.)
I recently removed a number of pictures from my Facebook profile that showed me drinking. I put off doing that for a long time, because it felt disingenuous to artificially modify the image projected there, because I have nothing to hide in that regard. But because the occasion of my concession to have a drink is so rare, it is usually an event unto itself for my colleagues (or a Kodak moment). This had led to a disproportionate number of those types of photos online, which I eventually realized justified an intervention on my part in the name of accuracy. But in general I don't try to mold my image so much as I try to mold my life.
Obviously alcohol should not be abused or used in excess, so that means it should be used with care. This is due to both God's statements about drunkenness in the Bible, and the clear practical realities. I personally see no reason not to totally abstain from drinking as well, but I would do so based on the potential consequences, not because God prohibits it. And I would also advise being carefully about judging others for their choices in that regard. But as for me, I will continue to do so sparingly, when it seems appropriate for social reasons.
