Is the daughter in question a well balanced and healthy person? If so, then calm down and move on. All you will succeed in doing is worsening things.
We all have things from our childhood where we feel our parents should have behaved differently. That said, now I’m on the other side of that relationship and have two kids, I understand better the moments my parents didn’t get overprotective and appreciate their judgement more.
However if an aged neighbour fed my kid whisky, I would not be cool about it. To be fair, my son would spit it out and tell him exactly what he thinks. The boy has his father’s intolerance for things which are not on his terms.
