Hinduism is a way of life, a law that governs all action. The word "Hindu" comes from the name of the river Indus, which flows 1800 miles from Tibet through Kashmir and Pakistan to the sea. As Taran explained it is based on his or her mentality of what he or she thinks. I really do not think so in today's world men and women would really think religion or belief coming in the way of their relationships. I am sure you would have heard of the great bollywood super star Mr. Shah Rukh Khan who is a Muslim and married to Ms. Gauri Khan who is a Hindu. Also there is Ms. Aishwarya Rai(former Miss World 1994) Bachann who is a native from the state of Karnataka who is married to Mr. Abhishek Bachann son of another super star Mr. Amitabh Bachann who have their origins from Uttar Pradesh a state in the northern part of India. And of course Hindus as a whole have a lot of respect towards other communities. Hope that would have helped you.
