Hahaha interesting link! True, Astrology doesn't play a role when it comes to matching but the date and place of birth does impact that account when considering an individual's lifestyle, culture and development.
By the way, the data you've pointed out is highly inaccurate, at least to what you're implying. It's mentioned "online dating matching", not "accurate worldly matching". A person's compatibility with another heavily depends on the calculation of, 1) desire control and effect, 2) development, 3) properly categorized personality type (and don't go crying about how stupid "control of desire is"; I'm well aware of your answer). And exactly how many people, and what kind of people, have taken up the online dating? I'd suspect those who haven't a chance in real life itself OR those who love messin around. The story's pretty interesting from there.
Secondly, although it's true a lot of educated Hindu (especially those who have international ties) look for partners beyond their borders, the fact that Hindu males are not compatible with Hindu females is completely bogus. Clear eye on social life here is evident enough to show that; I've got plenty of Hindu (and Muslims) who have had relationships with the same and different castes alike, even Atheists. Not to mention, being a Demi-Atheist (my Jewish, Hindu, Buddhist, Pagan, etc. knowledge is out of sheer curiosity alone) I have had relationships with Hindus, Athiests and Christians alike, and they've been pretty well.
But I don't mean that their calculations could be "wrong", except for what they have in their plates. After all as I said, they may be blokes just messin around, and if that's the case then obviously they're lookin for a chance to show off to their friends.
But this thread ain't about settling disputes, so enough about that. It seems you've got too much time in your hands. XD What's with you and your prejudice?
