Good grief. It's not a library, it's a mural. This isn't an archive of historically important but plausibly controversial artwork being purged for thought crimes, it's a fucking school wall. Kids and staff have to walk by this thing every day. And there's a dead indian on it front and center, and a bunch of slaves working in a field. It's... it's just not appropriate artwork for a public space.
And all this hand wringing is completely insincere anyway. If some random school in Arkansas had decided to repaint a mural with similar content, no one would care. But this is San Francisco, so of course Bari Weiss gets to write about it int The Times and pretend it's some kind of liberal disease.
