The Lowry Academy is part of the United Learning Trust, which runs some private schools as well as state schools, and has a Christian ethos (it sounds likely to be more Catholic than protestant.
As for all the comments about the article being from a source which has an agenda? Newspapers and broadcasters, including local papers that have reported the story - including the one that actually outed the specific school in question - have an agenda. Social media has an agenda. I think at least a long established human rights organisation which has researched and thought about its stories is likely to offer more informative and thought out articles.
I'd like to draw attention to the number of books on this list that have been pulled because they are about sexism, racism and other prejudices - generally criticising them not advocating them. Black women writers of at least one banned book on the list include Zadie Smith, Bernardine Evaristo, Chimamanda Ngozi Adichie and Jandy Nelson.
It all started with a book by Laura Bates about misogyny, considered too disturbing for staff as well as pupils. I'm a school governor, now at a secondary school. I have two sons, one in year 12 and the other a first year university student. I find the levels of sexism, racism and hatred being spread on social media terrifying, and think that it's important that staff, governors, parents learn about these issues because they're scary - and that girls and young women, boys and young men, are able to access books and discussions about the issues that face them as they're growing up and learning that challenge the hate and offer some advise to those facing abuse, not just the social media personalities making a fortune promoting hatred and abusive behaviour.
