Here are the bare facts:
1. The weather underground is no longer around. It hasn't been around for 40 years.
2. The Tea Party is.
The Tea Party today is far more dangerous the WU ever was politically speaking. It's a rebranded subsidiary of the GOP. It uses threats of violence to get its way. It votes for radical evangelicals and savages who selectively enforce the constitution. First amendment? Bad. Second amendment? Good. It's full of pork loving congressmen. It's also a group where there are high rates of people with weak bladders. That's extremely radical.
