It's simply amazing how people can twist Scripture to justify whatever their favorite sin is. It's no wonder that our country and our churches are in the shape they're in when people would rather attempt to make themselves feel less guilty for doing something God would not want us doing(and makes it quite clear in His Word) than to just live for God and tell others about Jesus Christ.
Go try and hand someone a Gospel tract with a beer in your hand and see how serious someone will take you. Go try and talk to someone about Christ while sipping on a Jack and Coke. I'm sure they'll take you seriously....
The Bible has been quoted quite a bit about this topic, and people would rather wallow in their pet sins than to gain wisdom from God's Word. But without those verses in play, these two should be enough to stay away from alcohol:
Abstain from all appearance of evil.
(1 Thessalonians 5:22)
It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.
I can think of A LOT of evil things that are caused by the very existence of alcohol. I've been a part of them, and I've seen them first hand. There is a lot of evil surrounding the use of alcohol. God is not a part of it, and God is certainly not glorified by it, and to assert as much is foolish. So yes, we should abstain from alcohol just on the basis of the appearance of evil.
I know several alcoholics and several who are trying to stay away from drinking. If they see another Christian man drinking...we're doing nothing but giving them the occasion to stumble.
Again....for this to even be a question is silly, IMHO.
