The library is a safe space... To explore ideas. It is not a safe place to avoid seeing dissenting views. The right-wingers who have been mocking snowflake liberals now want the libraries purged of anything they deem "offensive" from a narrow definition of conservatism. Society as a whole seems afraid, and it is manifesting in fear of technological innovation as well as philosophical disagreement. I think most people don't really want freedom if they can get an illusion of security through authoritarianism, especially if it comes with a veneer of virtue signaling.
