Yes intercaste and religious marriages are still not acceptable in some places in India. It is fact that it hurts the feelings of orthodox people and people who blindy follow caste system. But no one know the real meaning of Caste system as it is build my people only to just put some restrictions which actually is against god.
God have given equal things to human like blood, body, feeling and only intelligence, thinking beliefs change from person to person. According to history, Hinduism is old one and is most popular one know when mankind came into exitence. Other religious caste are developed gradually and most by some man who took birth on the earth.. So believing is the main thing here as all castes are founded considering the fact that some power exist which we call God.
But in any caste there is no procedure to marry a particular person or not. However intercaste or religious marriage are making society to sperated more than combine and stay as one..They should be encouraged and bling belief should be ignored as religion is just a belief not more than that.
