So, is this a good summation of your opinion:
All bookstores must sell all books.
If a bookstore finds out that some of its customers do not like a particular book that the staff of the bookstore also do not like, they must continue to sell it anyway, since they must carry all books ever printed.
If a customer does not like the fact that a bookstore has a particular book that the customer finds offensive, the customer must quietly leave the bookstore. S/he is free to go to another bookstore, but this store must also have all books in it.
And all bookstores must be very damn large in order to not make any choices about what books go on their shelves and instead stock all titles ever published.
