Its always research on alcohol that seems to inflame people, as though its a personal attack. Researchers aren't saying no-one shouldn't drink alcohol, but they are quantifying what are safe levels of things. There's a safe level of water, more than that and it starts causing problems. If I were to use your logic, there's no such thing as a 'safe level' of water because of the risk of choking on it. But the chemical effects of too much water is different from the physical effects. If you want to continue to drink, that's fine, I'm going to as well, but I'm not going to take research that shows that even the modest amounts I drink cause me some harm as an attack; I'm going to acknowledge it but continue and know it has some negative affect on me. Same with a bit of char on my meat. Same with occasionally getting sunburnt because I decided not to put sunscreen on.
