Dear Fawaz please get knowledge and then comment on any religion. The caste system is not a part of our religion, and the word Hindu refers to all who live to the right side of Indus river irrespective of ones religion.
Only ignorant fools can get bliss in their ignorance about our religion, But those who know it well only they can see the things as they are and relish at each and every moment the nectar coming from our scriptures.
