The issues with Intercaste love marriages are only in India. People of the western culture have peace with it. They literally don’t have any issues with people marrying anyone. But, the caste system has been deeply embedded in the Indian culture so much that we have seen people getting killed if they marry the love of their life if their love is from other religion. It is so dense that out of fear people start searching for a love marriage specialist.
This they do so that the lovers can live in peace even after marriage. However, the courts and the legal system also protect the couples who are threatened by their own families. If the children can talk to their parents about their love openly and show them the big picture, then the parents might get convinced. It is just the way how to tell your message. We have seen this a lot in movies. This can happen in real life too.
If the kids are independent and live away from home, then they can easily have love marriage and live happily. There are many couples out there who, because of their jobs live away from their homes, live happily with their partner from another caste. So, in order to be the love marriage specialist in your case, you have to have the convincing power to talk to your parents and let them see the worldview of the things. Educate them about it, tell when what you actually feel. Tell them to move on over petty things like caste. Tell them stories from other love marriages.
