the presentation is very complete, I am not a Buddhist, but it is not wrong to know the budha religion elements for the knowledge of history and the term in budha.
India is majority Buddhist and until now they still dominate Buddhism.
in my teaching to teach harmony in religion, we do not want to disturb and force the belief of people around.
humans have the right to choose their respective beliefs.
"living in peace" will be beautiful even though surrounded by different religions. Thanks @reddust
