Perhaps if you would have actually read the article yourself, or done other research, you would also know that you're still wrong. You're still an idiot. Genes do not control what we do. While genetics can have a factor on alcoholism, it doesn't mean that it's a direct addiction to alcohol. Certain genetic factors can make one get a better or stronger high from alcohol than those who do not have the same genetic makeup. Simply because someone does have the right genes, does not mean that person will become an alcoholic, or even drink for that matter.
Your entire argument is invalid, because genes cannot and do not control whether people drink or not, or the impulse to drink. They can simply control the feelings associated with drinking. You might have someone who gets an incredibly strong high from alcohol, yet he barely ever drinks. Then you might have someone who doesn't get much of a high at all, yet drinks all the time. This is even more evident in identical twins. Both twins have the same genetic makeup, yet one is an alcoholic, and the other isn't. If it was strictly based on genetics alone, both would have to be alcoholics, yet that isn't true.
Yes, while some people who have had alcoholic parents or other family members might have a better chance of being an alcoholic, you're way over generalizing as in saying it is in every single human beings genes to drink. It's also in our genes to survive, to eat, to drink, and to breathe. If I kill someone and start eating the flesh and meat off their bones, using your logic I can justify that because it's in our genes.
