It’s not censorship; it’s a private enterprise that can set rules as it sees fit. You’re free to yo-yo to explicit music as much as you like—and I certainly do—but it’s a family venue and sets rules how they choose. Personally I’d prefer they allow a little leeway and just deduct points for stuff that crosses a line, but it’s not my call.
Also, this thread is crazy old and probably not worth dredging up.
