I think your base assumption is flawed: just because we've been drinking alcohol for millennia doesn't mean it's safe or good for us. Natural selection doesn't magically fix everything; there needs to be some sort of selection pressure, and "dying a little bit younger" is likely not enough to weed out people who don't get the "alcohol is good for you" genetic mutations. Especially when people who drink only a moderate amount of alcohol still overwhelmingly live through and past reproductive age.
Whether or not a drinker is an "active individual" may not affect the damage (or non-damage) alcohol does; there's no reason to assume that changes anything.
I like a drink here and there as much as the next guy, but I'm not going to pretend there's zero harm.
