That's quite the case of South Asian inferiority complex you got there, either that or a severe case of South Asian centrism.
That has to be the worst, most hypocritical justification. We can culturally misappropriate, and call some made-up newage nonsense tantra and claim pedigree from the Indian tradition, but if there is objection to this absurdity, it is because they have an inferiority complex.
What? That's totally irrelevant. We're not arguing Aryan-Invasion theory here, in which I could see why it'd be thrown around (though still not agree with it) we're talking about an obvious disservice.
Fortunately today, people don't need to travel back in time to historical Indian eras in order to enhance their sex life.
Yeah, just stick with your sex shops and leave 'tantra' out of this. Or at least have the good sense to know what you're doing isn't tantra at all. Have fun with that.
Sex has as much to do with real tantra as it has to do with life. That is to say, a great deal, but you don't find life in a sex shop. Tantra encompasses the full breadth of life, of which sex is indisputably a major aspect, but hardly the only thing in life. Moreover, the sexual practices in tantra are highly nuanced and impossible to practice without understanding the agamic self-cosmology, and practicing the other aspects of tantra, a vast field of yogas.
In fact it seems that the developed world is succeeding today where a much more conservative Indian culture is failing,
Nice, now you're attacking Indian culture. I don't even disagree with you; mindless conservatism is a huge problem in India, but this is as ridiculously irrelevant as your first comment about South Asian inferiority.
whether they are doing it on the basis of native Indian historical thought or if they are reinventing the wheel is quite irrelevant.
You know that by saying such things, you are ******* in the well of your own academic field, right? If you decontextualize tradition, you have no archaeology to speak of.
