fuck off you right-wing scum.
In the immortal words of Red Skelton and Mel Blank: "He don't know me very well, do he?"
corporations aren't people.
Au contraire: Though they DO exhibit most of the characteristics of independent lifeforms, corporations are GROUPS of people, working together for a defined purpose. This is true whether they're businesses, schools, labor unions, churches, political parties, special-interest group, or whatever.
I assume we're agreed that people working together as a corporation shouldn't have any extra rights beyond the pooled rights of the individual members. But should these people LOSE any of their rights, just because they're working together?
Should spokesmen for a corporation with ten thousand stockholders, when speaking on issues related to the corporation's purpose, interaction with laws, and its stockholders' interests, have any less access to the ear of a legislator than the ten thousand stockholders themselves? A corporate lobbyist is just a representative of those ten thousand people when they're acting on this particular common interest.
The legal system treats corporations as pseudo-people because it's a convenient way to interact with the people making up the corporation when they're acting as a group.
