Do libraries carry Mein Kampf? Would the books you suggest be categorized and contextualized appropriately? (… like all other books, and a job that I believe librarians already perform.) "Categorized and contextualized appropriately" might also mean "not on the shelf / by request, but available for research"; a good many books that are considerably less objectionable and of greater literary value already are in libraries, as there is only so much shelf. Again, deciding what merits shelf space is a function of the librarian.
But you see no qualitative difference between {a book written by a white supremacist, neo-Nazi organization; a fabricated text (i.e., propaganda); and a book the SPLC describes as "'widely revered by American white supremacists' and 'a sort of anti-immigration analog to The Turner Diaries', and attributed its popularity to the plot's parallels with the white genocide conspiracy theory."} and "The book Pride Colors by Robin Stevenson, which explains the meaning of the rainbow colors in the Pride flag"[1]?
What is the literary value of white supremacist drivel or a fabricated text to a community library? (I'd wager approximately none.) Versus the books being complained about (anything and everything LGBTQ+). (Definite value from helping people exploring LGBTQ+ topics for themselves, simply trying to learn about LGBTQ people, to helping non-homophobic parents raise inclusive, tolerant children who don't want to spread hate & intolerance, and which need only be checked out by those who actually desire to read them.) There is demand for books of the nature being banned here; I cannot see there being anywhere near the same demand for books filled with bile.
And again, the empirical position (and for some subsets, outright stated position) of the right is to remove any and all traces of LGBTQ media from libraries. (And more broadly, from society, as well.)
In this particular instance[1], we can see this in one of the complaints:
> “Our library should not be carrying ANY material about LGBT,” one person wrote.
and,
> “Family has 2 moms — unacceptable,” the person wrote of another book. They also complained, “This book makes LGBTQ+ look ‘harmless’ and acceptable.”
Someone else points out exactly your quip; what about equal representation?
> She continued, “You said taxation without representation. What about my representation in the library? What about what I want my children to read? What about the 4 percent [of] LGBTQ members in your community that you represent that only get 1 percent of the books? Are they not being represented fairly with their tax dollars?”
In the broader national debate, we've seen this pattern endlessly; "protect the children" is a wedge to open a fissure towards a wholesale and complete ban. E.g., see the FL Don't Say Gay Act, which started as objections that education on such topics needed to be "age appropriate" but was then subsequently expanded until is was a wholesale ban on education of numerous topics.
