Here is a study suggesting the opposite to your claim:
Light alcohol drinking and cancer: a meta-analysis
Abstract
Background: There is convincing evidence that alcohol consumption increases the risk of cancer of the colorectum, breast, larynx, liver, esophagus, oral cavity and pharynx. Most of the data derive from studies that focused on the effect of moderate/high alcohol intakes, while little is known about light alcohol drinking (up to 1 drink/day).
Patients and methods: We evaluated the association between light drinking and cancer of the colorectum, breast, larynx, liver, esophagus, oral cavity and pharynx, through a meta-analytic approach. We searched epidemiological studies using PubMed, ISI Web of Science and EMBASE, published before December 2010.
Results: We included 222 articles comprising ∼92 000 light drinkers and 60 000 non-drinkers with cancer. Light drinking was associated with the risk of oropharyngeal cancer [relative risk, RR = 1.17; 95% confidence interval (CI) 1.06-1.29], esophageal squamous cell carcinoma (SCC) (RR = 1.30; 95% CI 1.09-1.56) and female breast cancer (RR = 1.05; 95% CI 1.02-1.08). We estimated that ∼5000 deaths from oropharyngeal cancer, 24 000 from esophageal SCC and 5000 from breast cancer were attributable to light drinking in 2004 worldwide. No association was found for colorectum, liver and larynx tumors.
Conclusions: Light drinking increases the risk of cancer of oral cavity and pharynx, esophagus and female breast.

Further, as with all epidemiological studies on diet, there are plenty of studies showing the exact opposite (a protective effect of alcohol):
Not sure where your animosity and disregard for science is coming from, but it doesn't seem like you're interested in having a discussion, having made up your mind to simply ignore any evidence that doesn't suit you.
How about I drink anyway, still have a partner and kids, still drive (while I'm not drinking), live and visit in whatever country I have legal authorization to live, and I shitcan your opinion. Cheers!
So a significant amount, but most people would say that's an acceptable risk to continue their lifestyle. For comparison, living in an urban environment has a RR of 1.20 to 1.40 for lung cancer.
That data is looking over a 1985-1990 / 1950-1990 time period. I wonder what the numbers are now with modern emissions improvements 30 years later, which are pretty big now!
And with electric car & electric heat pump transitions, how much better will it get on top of that going forward?
Also urban people tend to be wealthier, and also live longer.
I noted that it simply defines "light drinker" as <= 1 drink per day. It's not clear to me from reading the study how someone who drinks once every two or three days, or once a week, would be classified. The authors note some of the studies they incorporated in their results considered occasional drinking as "non-drinker" while others did not, so it seems that it was not consistent. However, it seems that in some cases the "non-drinker" category means people who completely abstain from alcohol.
Presumably you're right, they would be less likely to smoke, and I would imagine also possibly more health conscious in other ways. The authors mention that a different analysis of 15 studies of alcohol use among never-smokers was similar to their own findings, but also caution that tobacco could indeed be having an influence on their results (or even a possible synergistic effect with alcohol).
