It's a normal argument for the time, but it is far from reasonable. The person who wrote the original response to me failed to respond to any of the logical arguments I was making, just spouted some outrage and moved on. So, normal yes, reasonable, no. The word "ban" in this context applies to legal or cultural actions where you make owning, acquiring, or reading a book disallowed. All that has been done is a company decided to stop selling it. You can still get the book elsewhere, still keep it if you own it, and still read it in any library that has it (which I'm sure many, many do). They are just spouting outraged nonsense.
