I would Prefer Love Marriage over Arrange Marriage, though I don't completely disagree with Arrange Marriage. Generation today has changed, and moved forward with a very high degree of self-respect, privacy and in terms of taking their own decisions.
Earlier, the common trend was that the parents decided whom to marry, taking into account the family history, members, their status, religion and other things which even their children never used to bother.
Now a days, the children decide for themselves whom to marry and spend their entire life with ... which is actually goood because you know the person inside out whom you're marrying. Both the persons are acquinted with each other and know each other very well which is a very goood thing to gel them together and take decisions
.
How much ever we say that parents are cool now a days and all, but somewhere even they tend to feel that we never got the chance to see a boy/girl for our children, that hurts them ... but they never show. I am not generalizing it, but lot of parents agree just for the sake of their children so that they can be happy after marriage.
I'm of the opinion that, even if parents oppose Love marriage, they should at least give the Liberty to their children, a chance for their children to know the person they are marrying ... how much ever they can. They can set up a meeting, talk to each other, let the boy - girl talk to each other in private. If they like each other ... they can ask them to spend some time with each other ... like for some days or months ... in that way both of them would be able to know each other, though not completely .. at least they will know how much compatible are they with each other.If it works, well and goood ! If it doesn't ... no one is at the losing end.
