"Doesn't mean anything" is a shorthand for "not well-defined" and "means completely different things to different people" which makes it a useless word for any serious conversation.
The context I gave should make it clear what it means. The fact that a word might mean different things to different people is no real excuse to avoid a conversation.
How do you propose to have a conversation about whether X is good or bad when one side defines X as "bad things" while the other defines the same word as "good things"?
