Many poor precedents are grounded in strong emotional reactions at odds with basic principles, and in my opinion obscenity cases are a good example of that. Still, the classification as obscenity is more about the form of the speech than its content. In fact the more content there is, in the form of either expression or artistic value, and the more the form contributes to accurately conveying the content of the speech, the more likely it is that the speech is considered protected, even if the form would otherwise be considered obscene. I'd rather the courts didn't get involved in trying to decide whether a controversial turn of phrase has enough merit to warrant protection, but in any case I don't think you can extend the principles underlying prohibition of obscenity to exercising control over which information can be conveyed.
