"I know I am in the right so I hold my head high knowing their day is coming"
This right here seems to be the biggest problem with conspiracy and conservative types, the unfailing certainty of their righteousness, this seems to be why you can't reason with them, and if you tie in their religion then they start with their surety that "God" is on their side.
Maybe if they had the strength of character to deal with their self-doubts rather than bolstering their infallibility by dismissing their doubts as weaknesses, maybe we could get somewhere with these people.
