You can just Google shit dude. Do the bare minimum some time. It's embarrassing how confident you fucking dorks act given how catastrophically ignorant and helpless you are at the same time.
I develop my entire worldview through adversarial conversations on the internet. If you don't spoon feed me sources for even the most well established facts my ego will starve and I'll say something bigoted but pretend you're the asshole for taking offense. Yes I'm a liberal, how'd you know?
The comment was very ambiguous, and I had a feeling they had something in particular in mind. If they showed the one they were thinking about, we could better talk about the same thing.
"Contras" is not ambiguous. That would be like calling the "Mujahideen" ambiguous. It's a real group with a name and historical record, and the US government funded them because they were fighting eViL GoMmUniSm.
Oh yeah, the US funded and armed the Mujahideen (aka precursors of the Taliban) too, by the way. Same story different name/continent.
