As far as I know there isn't any scenario where drinking wine is healthy and I say that as a french guy. Alcool being healthy or good overall for your health is a myth no matter the amount. You might gain some on some aspect but overall it will never be better than good food and a glass of water.
Yes, this is boring but science is pretty clear about it and we obviously had this debate many times here.
Just because we make a lot of quality wine and good food doesn't make everything healthy.
I think a long time ago kids were getting a bit of wine at school lunch so we are not an example here. We have a wine lobby that tried very hard to reinforce the idea that a "little glass" of wine is good and that without excess it's fine. Truthfully no amount of alcool is healthy. I still drink a beer here and there but alcool will never be healthy and I know it.
I'd say that, in reference to small amounts, there's a difference between "bad for you" and "won't actually harm you" but I'm not going to argue with your point
Being a Group 1 carcinogen, let's analyze it with other carcinogens in the same group: is there such a thing as "won't actually harm you" amounts of asbestos? What about "won't actually harm you" exposure to ionizing radiation?
We don't know which DNA damage will turn into cancer, but each exposure to a group 1 carcinogen is another lotto ticket bought to see if you won cancer. You will never buy a lotto ticket that doesn't have a chance of winning.
ETA and then there's the non-cancer effects that just increase cardiac problems and stroke risk.
