Our religion originated around the time of the ancient Egyptian and Greek religions and still survives till this day, despite the 1000 years of Islamic rule and 200 years of Christian rule. There must be something be special in Hinduism, because it still is the 3rd biggest religion.
Islam is the best religion in the world. Sunni Islam is not a religion!. It is a branch of Islam. There are two branches, Sunni and Shia. There should not be two branches in islam. Islam should follow the same rules but shia left the sunni religion and made a new branch. The main branch is Sunni which is 80% if Muslim population. I don't like Shia.
That's why I won't say religion x or irreligion is the best religion. It's the diversity that's the best. We need to safeguard it and we need to learn to coexist with our differences. Having said that, what we do need to remove from religion is dogmatism and interventionist ideas.
Hinduism is a great religion because Hinduism, lets you do whatever you want, you can follow ideas from any other religion. In Hinduism you are not restricted from doing anything. You may worship a idol or you may not, it all depends on what helps you get inner peace.
Chinese folk religion (Chinese popular religion) or Han folk religion is the religious tradition of the Han people, including veneration of forces of nature and ancestors, exorcism of harmful forces, and a belief in the rational order of nature which can be influenced by human beings and their rulers as well as spirits and gods.
