As others have pointed out: this is the society becoming more liberal. The great triumph of liberalism has been removing the government's influence on social norms, and how we engage non-violently with one another in general.
Where the modern Left has gone off the rails is insisting that we also cannot reinforce good behavior and shame bad behavior, mostly the latter, through non-violent social interactions.
It's great that the government can't prevent adults from wearing pajamas in public, but you'd also be right to make value judgements about the kind of adult who does that.
I tend to make more negative judgments on people who look like they've spent the last three hours coiffing every individual hair follicle. All I see is the human equivalent of a whitewashed tomb.
