Libraries are safe spaces for minorities and the LGBTQ+ community. Books in general spread awareness and raise empathy and can also help struggling young people understand that they are not alone.

That quote isn't saying people of these communities read or use a public library more than those who aren't; it's pointing out that the erasure of public safe spaces and resources affects groups that benefit from their existence more.

All of that doesn't even mention the content that was likely present in those 500,000 books.
