If you’re an activist and someone pushes you downs a guns & ammo path, you should probably assume that person is cop or spy.
And yes, I’ve mentioned this before: If someone in your group promotes any kind of violence, you should ask, loudly and publicly, Are you a cop?
Even if the person is just an idiot (as opposed to agent provocateur), by calling him or her out you highlight how the police/feds have attempted to short-circuit activist movements by pushing them toward violence, and illegitimacy.
This isn’t paranoia; it’s just good sense.
