It's still conspiracy theory mentality. It's the exact same thought process that leads credulous morons (as opposed to the deliberate assholes using conspiracy to mobilize said credulous morons) to believing the Sandy Hook Massacre is a hoax, or that 9/11 truthers are a legit. "Other side -> Can't trust other side -> They're trying to trick me -> This person is on my side so they must be right" is the mental channel through which all conspiracy theories flow, and one type isn't any more sensible than any other.
