The weak mind falls inevitably into misinterpreting emotion for facts.
All our major religions built themselves around common passionate sensations and then over time organized cocoons, like churches, synagogues, mosques, etc. that regurgitated this emotion as spirituality.
Practitioners tended to meet early in the morning, on a Saturday or Sunday mostly, when still not quite awake.
Flash chemical passions account for nearly all loyalties. Place a baby in front of women, and it will swoon for their breasts like they have swallowed a barrel full mescaline cactus.
Likewise, men at sporting events demonstrate allegiances on the minor triggers of colored jerseys. There would not be Christianity if Jesus died during the playoffs.
The frailest minds gravitate towards fidelities that can be horrifyingly simplistic and even moronic. These people will, without any discernible catalyst, announce what their political party is or who they were in an earlier life. These characters are essentially harmless except when granted some play in decision-making activities like Presidential elections.
