I agree the post-consumer recycling passes the buck from manufacturers to consumers. I think your point can be made without making it sound like it is because "Karens", which is just a way of saying "thoughtless women", are taking frivolous trips.

It would be similarly ineffective to make a comment about just men and their unimportant, pointless trips.
