And, yup, the tendency in this sort of thing is to generalize. My main problem with the lady next to me was that the kid didn’t really want to be there and clearly wasn’t mature enough to sit quietly  (though a lot of adults seem incapaple of that as well!).

As for your son, well, as my parents used to say, every family is different and I know that even I was exposed to things that many people of my generation would have thought inappropriate — though more on the sexual end of things since I was big fraidy cat when it came to horror and bloody violence.
I almost mentioned it in the article, but one of my earliest movie going memories is being dropped by mother with another kid to see the “M” (”for mature audiences”) rated “On Her Majesty’s Secret Service.” I was six years old and I’m still not sure what I made of all those bed scenes….

As to the whole violence versus sex issue in what we try to protect kids from, I will almost certainly revisit that issue later….
