Again, you are ignoring all the vast body that refutes your position, of watching normal Buddhists or Muslims or Hindus of India 100-200 years ago that stopped and prayed at every shrine along the Grand Trunk regardless of what God or Religion the shrine was dedicated to. You are ignoring the Taoist traditions that redily adopted and recognized most any religion; of the Native American "powwows" where different tribes gathered and told their own tales of religion and origins and the other nations paying attention and saying "that's interesting"; of the modern Ecumenical Movement, of the Romanization of the Greek religions as well as the Christian practice of adopting and re-purposing most any celebration from Christmas to Easter to Passover to Pentecost.
Religions have never been monolithic and have all evolved and changed over time.
