Why Indian parents feel insecure about love marriage ?

When you are over 21 years old and when you love someone and when u happen to be in India...i hope you could understand this question. There have been umpteen number of incidents regarding this issue. I, being a teenager, happens to support "for". Well why is that? In my opinion parents come first, yeah accepted. They have taken care right from the kid, yeah accepted. They care a lot about us, yeah accepted. They know whats right and whats wrong for us...hmm...here where the problem arises. They see whats right and wrong in thier point of view. When they were teenagers...well majority of them would have experienced these incidents either personally or their friends might have. O.K...thats not a problem. When we take India into consideration, the whole picture of family is different. Here kids live with their parents, if situation permits, life long. This is unlike western countries where kids are told to make their own life some years after adolescence, atleast in majority of the families. Coming to the point, why the parents feel insecure. First, they see the consequences around them all the time. Teen age pregnencies, casual sex, partying stuffs, deviating from education et al. Doesnt a person who is matured at brain can't take his own decisions? The person in this context refers to both the father and the child. Looking from a parent point of view, yes what he is doing is perfectly correct. Well which parent will ill-do to this child? He has taken care of his child right from the birth. He has taken all the kid's decisions, can't he take this? Some might argue he is the best person to take the decision because he is the only person who is really concerned. Forget friends man! this is blood!! Well...really ask the person who loves. What would he say? They will say only one thing..."if you have ever loved really, trully, you will know how i feel"...i guess that will wound up.
