@victor I'm just confused how the Protect Act could possibly supersede Ashcroft v. Free Speech Coalition -- that's not how it works.

It seems to me like they're just trying to discourage it by threatening the public with obscenity laws and hoping nobody has enough money to hire lawyers for defend it (which would be quite an unsavory and difficult thing to do in the eye of the public). But if you really wanted to fight it and had the resources you should win easily. Congress can't override the SC here, so they're just trying to sidestep them
