Who does Mike Tidwell think he's fooling?

Tidwell claims to have no idea why the government might think he's an "environmental extremist"

There was no civil disobedience at this event. No one was arrested. No county, state, or federal laws were breached. The entire affair was utterly peaceful, above board, and appropriate. Political demonstrations exactly like this happen a thousand times a day in America. There were no media reports of anything unusual.

With a climate disaster looming, I’ve worked very hard for many years to promote clean, renewable energy. But perhaps the greatest contribution I’ll ever make to this cause is the action I’m taking right now: standing up and working hard to keep government itself clean.

Some pretty good clues are here, in a piece by Tidwell himself

The entrance to a major federal agency, one whose politically appointed leadership has been widely condemned for suppressing scientific climate reports, was effectively occupied.

For the rest of the day, the occupation was major news in the nation's capital. The main NPR station broadcast hourly live updates of the ensuing standoff with police, repeating the activists' call for open science and clean energy. A Fox News helicopter hovered overhead, filming everything. And more than 150 newspapers picked up the Associated Press story about this day of principled activism in the face of politicized science.

As director of the U.S. Climate Emergency Council, I was one of the chief organizers of this event and played the role of main negotiator with the dozens of police and Homeland Security officials who eventually arrived to try to coax the activists off the ledge.
