Biased would probably be more appropriate than naive.
But no, I do know that and don't think it ruins our liver everyday. Our liver can tolerate so much of it, which is likely why it has developed to be our only regenerative organ too. Now, when the body is producing its own ethanol daily does it produce it all in one go in a short period of time? No. What happens afterwards? Does the ethanol just flow through our bloodstream? No, it is catabolized because if it wasn't we would die since, well, ethanol is toxic.
http://en.wikipedia.org/wiki/Alcohol_intoxication - You die of alcohol poisoning if you consume so much a short period of time that your body cannot metabolise it quick enough to prevent death through toxins in your blood. Toxins being your blood kills you because they kill cells!
Any of amount of alcohol you consume is putting more pressure on your liver to get working and it kills cells. Sure, a few grams isn't going to kill you, just like getting punched in the face everyday won't kill you, but it's still better than not getting punched in the face everyday because you need to devote less resources to getting your skin on your face patched back up, same applies to your liver and other cells that ethanol kills when floating around your bloodstream un-metabolised (namely your red-blood cells which alcohol can enter through the membrane of and alter their structure).
I am being biased in trying to defend this insofar that I'm looking for specific studies to defend my view here, now, I'm often open-minded, but here I'm merely sceptical, because I know of the effects of alcohol bio-chemically, to come to certain conclusions that alcohol gives. Given how large alcohol is in society and that funding for research comes from society I would expect most studies to say that it is good even if it wasn't. Hence my scepticism.
Anyway, here's another study:
http://www.medicalnewstoday.com/articles/279480.phpThese studies, this one here and the one I posted before both try to eliminate the correlative issues concerning epidemiology and nutritional science in general, which is why I place stronger emphasis on them than I do a dozen other studies that contradict them. It's just better science. Now, I'm not going to claim we know for sure whether any alcohol consumption whatsoever is always, holistically, unhealthy - science cannot prove that and we humans never will be able to. What I will claim however is that there's still good reason to believe that it is true.
I mean look at this:
http://www.medicalnewstoday.com/articles/273528.phpThat website you gave me earlier was still spouting the nonsense about fat being the cause of cholesterol increases which are the cause of heart disease which has not been proven causally once.
It's not convincing, yet the reasons why alcohol consumption would be bad for you are quite obvious given what it does. Hence why common sense should tell you, alcohol isn't great for your heart. What does it do, what is so obvious? Here:

Ethanol is precisely that. Sure some ethanol won't insta-kill you because our body can convert it into non-toxic substances. Same applies to EVERY TOXIN THAT EXISTS. In a sufficiently small amount no toxin, even the worst snake venom, would kill you. Now, the reverse is true that everything that exists will you kill if there is enough of it. Too much water in your blood and you die of water intoxication.
So what I really mean by "toxin" is that it will kill you when it is in your body un-metabolised even in relatively low quantities compared to "non-toxin" substances.
