That's not what the decision says. It says the right of political speech is extended because of either citizenship or association. Your statement would invalidate any restrictions on speech, no matter how necessary to preserve the rights of others. Is that really what you want?
Yes, it is. Absent "clear and present danger to the public" there needs to be no restriction on free speech.
Please tell me which kinds of speech you'd like to see restricted.
"Clear and present danger" was overturned about 30 years ago.
But even using that standard, I fail to see how funneling unlimited amounts of money from anonymous sources through corporate shells and into the (already corrupt) political process can be seen as anything other than a danger. McCain-Feingold had to go, but this is not the answer.
No, actually it wasn't. Please show which case overturned Schenck.
Sorry you fail to see that. I fail to see how allowing the gov't to ban books can achieve anything other than despotism.
