In my opinion, the lecturer/professor is a pompous bully. In my various college careers, I've had several such. I'm neither impressed nor intimidated by them. After the session, I usually approach to speak to them privately. Calling them out in class is to challenge them on their own territory, and as Sun Tzu points out in The Art of War
, this is not facile ground and they usually become defensive. I returned to school recently to finish a left-over degree and had a conversation with a professor about how he wasn't in loco parentis
to us students, so it was inappropriate to say he was "disappointed" in us. I said it was perfectly fine to say he was disappointed in our work or performance, but to say he was disappointed in us as human beings was not his place as an educator. He agreed with me and said he spoke thoughtlessly. The fact that I was about ten years older than he probably carried some weight re: the in loco parentis
In the case under discussion I would politely but firmly explain that the behavior was unnecessarily impolite/harsh/aggressive, and if the lecturer acted on wrong assumptions, correct the misapprehensions. If he continues to have a problem, I'd take it to the department head. I think pointing out that you were 'wrong' the next day was vastly inappropriate and a sign that he felt threatened by your superior knowledge of meditative techniques. He was attempting to firmly establish himself as the Alpha in front of the herd. This in my opinion reveals a deep sense of personal inadequacy, low self-esteem coupled with an enormous ego, which is why it's difficult for him to admit when he's wrong and why he would assimilate your information, perhaps even unconsciously, without acknowledging your contribution. If you want to really undermine his expertise, ask him about the phenomenological relationship and similarities between anapana sati and Jewish Meditation.
I also grow weary of the tendency of academics to somehow view their artificial Jenga-tower of superstition as somehow superior to "organized" religion. If the Ivory Tower isn't a cathedral erected to the Academic ego, complete with High Priests, rites and rituals, and a whole bevy of superstitions, then I'm the emperor of ice cream. I saw through this mythos of academic supremacy as a dewey-eyed freshman of nineteen. As a gummy-eyed senior (for the third time) at 52, I call a resounding BS. Academia is as full of crap as a Christmas goose. Perhaps the lecturer realizes his feet are made of clay and he fears the day when someone with real-world experience reveals the man behind the curtain.
See, two can play this analysis game.
Perhaps should get his own prime-time television show
