What do you think is hypocritical about not believing the rights of the individual should automatically translate to businesses? It seems obvious that they should not.
So, since we do not have laws over atoms, neither should we over molecules, etc until we reach humans -- clearly I'm taking your argument to absurd levels, but it does illustrate my point. Something something seeing the forest for the trees.
I don't quite get your point regarding atoms. What I was trying to say is humans are not the only "person" before the law - corporates, trust, clubs and other bodies are also persons, and should have similar rights (including free speech).
If you can get congress/a court to designate an atom as a "person", then sure, the rights would extend to atoms too.
The real irony is wanting the leader of your government, the President, to have absolute power over speech, but then throw up complaints about private organizations trying to combat the dangerous messages coming from the government, because that's censorship.
