Here's my take on it:
The Salt Lake City meetup group wanted to create organization to better coordinate amongst its members and to reduce the chances of agent provocateurs (a very real phenomenon) causing damage to the Ron Paul grassroots campaign by utilizing the technique of black propaganda. The original poster in question was angered/upset at such organization, preferring that people campaign in a decentralized fashion, probably for ego reasons. Staying in the group was frowned upon by the SLC organizers, who removed him from the meetup group due to their desire to not artificially inflate their numbers.
After being removed, the OP took it personally and projected his anger upon the entire Ron Paul campaign, and threw a tantrum.
Now, how close am I to the truth?
