That got pushed back to 2002, meaning half the book was written in the immediate aftermath of 9/11.
Sticking to just that feels irresponsible and disrespectful toward people facing actual oppression in the here and now.
Suppressing music and art just lets them do that without having to say so.
Attacking the art is a way of attacking the people who make and enjoy it.
Where we get a little escapism is in how your characters deal with that.
But while we real people get paralyzed with doubt or despair, your characters know exactly how to fight back *and win.*
Don't let these fuckers win.
