So then you don't believe individuals have the right to organize to petition their representatives? Because any organization is going to mean pooling resources into a legal structure...like a corporation.
That's a good quibble. People should be allowed to organize. I suppose there should be a distinction between political organizations and profitable ones.
So a group "Whigs for America" pooling donations is fine, but a for-profit corporation spending millions on lobbying would not be fine.
The difference being that the former group is a non-profit collection of people concerned about some aspect of government.
