Terrorism is the manipulation of fear for political gains. By that logic, Senators who voted for the National Defense Authorization Act (NDAA) are terrorists.

Sounds like treason to me when you consider what they passed and their position of power:

trea·son
noun
1. the offense of acting to overthrow one’s government or to harm or kill its sovereign.
2. a violation of allegiance to one’s sovereign or to one’s state.
3. the betrayal of a trust or confidence; breach of faith; treachery.
