I'm not agreeing with one word of Kagan's article, it is pure crap, phony 'analysis' disguising a naked attempt to circumvent the First Amendment. I'm saying the Zionists are having remarkable success as the article does show. The first law she 'analyzed' was prima facie absurd, a complete revocation of the First Amendment, and should never have been written, much less generated a case for the Supreme Court.
The first law to which I referred was the Alien and Sedition Act, enacted by Congress in 1798, seven years after enactment of the First Amendment, which barred speech that criticized the federal government. This was enacted by the very same people who helped draft and enact the First Amendment.
So nobody in this country ever thought the First Amendment was an absolute as you seem to believe.
