Watching a library burn is tragedy. It's loss. Lots of things are mass-market, replaceable but every library will hold some things there are very few of. Maybe no others. And when things are gone it can be impossible to bring it back. I know, I just spent 5 years of my life on a project that as good as it is can likely never be complete.
Watching a library burn because the fire was deliberately set is a straight-up obscenity. That it was set by fascists makes my blood boil.
War never changes.
