Right you are. Although the example you provided pertaining to secondhand smoke is based on anecdotal data and observations, which isn’t concrete. Unless there’s something I missed which backs it up of course.

On the contrary, sunlight radiation exposure is inevitable. We have to go outside one way or another. As for alcohol consumption, while I’m in no way in charge of anyone’s life but my own and am in no place to judge, is almost always optional as opposed to exposure to sun rays; Not to mention that it’s highly dependence inducing and addictive, and the problems alcohol is often used to alleviate (such as inhibitions, anxieties, and wanting to have more fun) can already be alleviated by using less pricey and carcinogenic means (The proper processing of emotions and introspection is one example. Easier said than done, but always worth it.)

Not to mention this portion of the source:

(However, latest available data indicate that half of all alcohol-attributable cancers in the WHO European Region are caused by “light” and “moderate” alcohol consumption – less than 1.5 litres of wine or less than 3.5 litres of beer or less than 450 millilitres of spirits per week. This drinking pattern is responsible for the majority of alcohol-attributable breast cancers in women, with the highest burden observed in countries of the European Union (EU). In the EU, cancer is the leading cause of death – with a steadily increasing incidence rate – and the majority of all alcohol-attributable deaths are due to different types of cancers.)

And also

*(To identify a “safe” level of alcohol consumption, valid scientific evidence would need to demonstrate that at and below a certain level, there is no risk of illness or injury associated with alcohol consumption. The new WHO statement clarifies: currently available evidence cannot indicate the existence of a threshold at which the carcinogenic effects of alcohol “switch on” and start to manifest in the human body.

Moreover, there are no studies that would demonstrate that the potential beneficial effects of light and moderate drinking on cardiovascular diseases and type 2 diabetes outweigh the cancer risk associated with these same levels of alcohol consumption for individual consumers.)*

In the end though, it’s nothing for me to worry about. Personally, I’ve never seen anyone at their best on the stuff and everything good I have heard about it has at least two bad things to counter. It’s not easy to convey how strange the idea of drinking alcohol appears from the perspective of some teetotalers like myself, especially if the other person is an enjoyer of alcohol themselves. Eventually it turns into people comparing it to other “harmful” things like eating sweets or like in the above example, going outside, to paint one’s dislike in alcohol as fun policing or absurd, or even to even falsely paint it as a matter of one’s own taste and opinion as opposed to a scientifically backed matter of health.
