My question is fundamentaly what makes the faithful believe their answers have more merit than the answers of other cultures?
Am I missing something big here? Surely this question answers itself.
If people thought another cultures answers had more merit then their own, they would instead believe in the other cultures, which would thus make it their culture.
For example, if you're a Christian, but you believe that the Muslim religion offers better answers, then it suggests you believe more in the Muslim religion then the Christian, so surely you are a Muslim.
People believe in what they think is right. There are thousands of reasons why people think one thing is right. Helmets vs no helmet. Tubeless vs tubes. Religion vs atheism.
For example, if you had someone who was running tubeless, but believed tubes were better, then you have someone who's a bit odd. If you have someone who believes in one religion, but thinks of themselves as a member of another religion, is this any different?
