First: No, I Am Not A Fed.
I have been using this sobriquet in one form or another for over 20 years now. It started in the late 1990s with a couple friends after watching the original "Matrix" film. We each took on nicknames "Agent" plus whatever three-digit number we chose to express our sense of self.
So please don't try to claim the "Agent" part of my nickname means I'm a Fed. I'm actually one of the people the Feds unjustly target for harassment: White/Aryan, openly National Socialist, traditional, strong ethos and ethnikos, with nothing to hide. Even so, I have no criminal record and have never committed criminal violence of any sort, with or without a firearm. National Socialism is my spiritual path, not just my political preference.
