I think hate of plastics is an emergent form of elitism.
Upwardly mobile middle/upper class people who've sort of "maxed out" the amount of personal identity they can buy with regular plastic things can unlock a new level of identity by deciding that plastics are bad for them and eliminating plastics from their life, a process which conveniently requires buying a whole new set of things that distinguish them from their peers.
This is the only way I can explain how irrational and inconsistent plastic-haters behavior is. There is so much invisible plastic in their life that they don't seem to care about.
