You may not buy it but that's what the data shows. Now, you buying it versus you wanting to not believe it is another story. I too drink in moderation but that doesn't mean I'll act like it doesn't have negative consequences, however slight they may be. The study is not prescriptive, it's not saying people should give up alcohol, it's merely descriptive, in that it's telling the reader what's happening as a result of any level of consumption.
Frankly, nutrition science seems like a bunk field. Common advice is overthrown every few years and you can find a study that backs up any viewpoint you want. "you buying it versus you wanting to not believe it" is a weird statement to make in the context of such a sketchy science.
