When the left exposes the GOP's behavior, one of the ways that the GOP is good at shooting the left down is by clucking and crowing about conspiracy theorists.
It's effective because it brings up the images of X-files, dark conference rooms, old white men baring their teeth and rubbing their hands together gleefully, crazy people with tinfoil hats, etc.
The thing is, they have a point. When a GOP action has a bunch of undesirable effects, there's a willingness by many of the left to believe that every single one of those effects was explicitly planned out. It's a bit boogeymannish. Also, conspiracy theories imply that the people participating in the conspiracies know that all their actions are Legion-Of-Doom Bad, and do it anyway just because they enjoy being Bad.
I think there's a better concept to use than conspiracies. These people might not be consciously trying to destroy the world in the name of power. Instead, they could simply be slavishly clinging to their own justifications. Their actions might actually make sense to them, even while they weakly refuse to open themselves up to perspective, and cower back into their own closed systems whenever threatened, using circular logic as their last defense. They might not intend every single effect of their actions, because they might not even care about effects at all - instead only blindly following the dogma that justifies the actions.
In short, next time you're accused of calling it a conspiracy, shoot back at them that you think they're weaker than that. It's not a conspiracy. It's a cult.
