Yes, corporations are just like a person
No, corporations are not just like a person
Guess what we've been saying?
That the First Amendment protects the freedom of the people to speak and publish their thoughts, and corporations are owned by people, the participation of corporation in the national dialogue can not be limited by the government, since to so limit them would be to limit the people that own them.
Let's look at the actual case a little closer.
Citizens United is a political group - a group of people who got together to act because they believe in a political cause.
Nobody here would deny that a group of people don't have rights, being people.
Now, that group of people decided to form a corporation to make it easier for them to act in concert. Suddenly they lose their rights because of that? Why?
Other groups - legal entities, not just multitudes of people united - clearly have rights. Political parties, for instance. Or is someone here going to say that political parties have no right to freedom of speech too?
