You bring one case on bookstores. Here's a ton that relate to free speech/press, which is what gives bookstores their rights. You can go to the link, not typing out ALL of the cases, way too many! You need to realize the current court as already started throwing down some serious decisions that buck the pervious assumptions about many issues. Don't live in bubble, listen to what the judges have said and done. What I think or you think is irrelevant, it's what those six in the majority think that matters. Just like it was a few years ago when all that mattered was what justice Kenedy thought since he was the swing vote most of the time.
