Well...yes?

But I assume it’s the other way round. You pay premium to get, among other things, more quiet and privacy. Although there is no limitation and wealthy parents can book their kids in F should they wish to do so, the average J or F traveller assumes that she/he will be less likely to be bothered by families. If that happens, nothing will excuse rudeness, but I do think it perfectly normal for those individuals to feel uncomfortable.

when you fly economy, you are naturally more open to experience the full spectrum of potential travel related issues, including babies and loud families.

I really do not see the scandal here...
