They might be said honestly, and if the listener is sufficiently cynical, easily annoyed or superficial, the honesty of the expression can be dissolved.
As Amos says so well, any language can be devalued by misuse, commercial use, flippant use, thus fostering the avove listener characteristics.
I think one of the things going on here is that there are many people who go to therapy or, more likely counselling, and come away only with the husk of a vocabulary, having missed the kernel. They then use the words superficially, and others pick up on the emptiness.
On the other hand, to a cynic, anything can be reduced to meaninglessness. So, for example, the great game of chess becomes just pushing bits of wood around a black and white board. Chess is thus emptied of meaning.
