I really wish people would at the very least take this kind of stuff somewhere it's less likely to be seen by the people who are being spoken of. And especially if it's about kids, maybe take it somewhere entirely private where you know for sure the kid will never have to see it. Or just don't say it. But I feel like trying to make people not say certain stuff is way less effective overall than just encouraging people to be more mindful and considerate of when and where they say stuff.
