The only reason the subject of The Five Chinese Brothers came up was because the book was mentioned in a question post made by unassuming, which was answered on the same page where I was quoting myself to claim stump points. I quoted unassuming's question post, and effectively I was engaged in a dialogue with him. You were not a party to that dialogue.
My statement that the book had been banned from libraries came from Doug Miller, either as an indirect quote, or as an incomplete memory. I mentioned that my conversation with Doug had been in 2017. As a seller of books, Doug may well seldom visit libraries, because he sells books but doesn't lend them. It may be true that The Five Chinese Brothers is no longer in stock at any bookstore which sells new books. You have, as yet, not provided a link to any retailer of new books in your vicinity which has at least one copy on display or on order. The list of previously published books which are now out of print likely far exceeds the number of titles easily found, hence the existence of, and the need for, secondary market shops.
Your information that the book was not banned in Toronto libraries was news to me. I only visit the library to make photocopies. I have plenty of books to read in my own personal library. As Doug is the owner of the only store, (to my knowledge), of second-hand books in Toronto which specializes in children's books, I assumed that his statement was true.
You don't even live in Toronto. It's good that you looked into whether or not the book was, indeed, available in some Toronto libraries. I have no interest in having a copy of The Five Chinese Brothers transferred to my local branch because I have two copies in my person library, and Doug owes me two more from a trade.
The 'evidence' which you have been asked to provide refers specifically to the quote next to the red arrow in the screen cap above.
When have I EVER written ANYTHING, ANYWHERE, which would lead YOU to believe that I have EVER supported censorship OF ANY KIND, in ANY POST which I have made on the Internet, ANYWHERE?
If the Like I gave you for the split post is evidence in your eyes, keep in mind that it was given to you AFTER your post, and it refers specifically to your first statement, and definitely NOT to the second.
I should not have had to restate the same challenge with more all caps words, but you have either misunderstood your task, or you are talking around the question, because you are unable to justify your accusation.
THAT'S what matters to me.
