Those “national groups” have in the past written letters containing false and misleading disinformation. I have in the past written about such efforts and about how groups like the ALA and the NCAC support inappropriate material for children despite the law, community standards, or common sense. While I have not yet seen the current letter, I doubt it is significantly different. I look forward to reading it and deconstructing it, and I will assist anyone who asks me for help.
