Wikipedia has little influence on what's practiced in a seminar with the headline tantra. At the same time of course it's not simply about the stereotype it has.
One element of tantra is for example strong eye contact. You can go to a PUA seminar and hear a lecture by a guy about holding eye contact. That often leads to guys going out and being uncalibrated. If you on the other hand learn eye contact in a tantra seminar the resulting behavior is likely much better calibrated.
I feel we are using the word "tantra" in entirely different meanings.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
