I remember days where if anyone talked about kids, it was a horrific thing to do. They were evil, the devil, "all kids are beautiful, how fucking dare you

", etc. But now I see women openly discussing other people's children and what they think of their appearance. And I'm not talking about anonymous trolls who get courage behind a screen. I'm talking "real life", real people.
It's not my position to judge them or say whether they are right or wrong, because this is simply their opinion. Are they horrible people for voicing what others may actually have in mind, but find inappropriate to openly say due to some unwritten moral code of conduct that we've been abiding by for generations? Although we are well within right to say how we truly feel?
I don't think they are. But I'll ask this question, do you guys think that our ideas of what is moral and what is immoral has been shifting a bit? Are things that were normally viewed as unacceptable and rude becoming more and more tolerable?
