I think 80% of the pists on these forums can contribute to confusion of new users. The post itself is merely a citation of a Sutta, which is actually a good thing and can help people find out what Dhamma theories are actually too weird to be true (I think you know who I mean). As for the comments, well, tommit cannot even prove that these very words were said by the Buddha, let alone any other words we find in the Nikayas. Besides, his words that NOBODY practices the Dhamma we find in the Suttas, said on the forums where we have so many inspiring and dedicated bhikkhus and bhukkhunis, are utter non-sense unless he can prove he has clairvoyance. His claim that the true Dhamma is corrupted by other participants of these forums is also weird: He may know what the true Dhamma is only if he himself is at least a stream-enterer, which I think any new user can figure out for themselves in a matter of a few minutes.
I mean, there are posts by, say, Ven. Dhammanando, Sujato and Brahmali and those by tommit. I think, even if I were a new user I would be able to know for myself what sounds more plausible. Besides, well, calling people out on their… erm… malarkey can also work pretty well. So long what tommit said sounds about as plausible as me claiming nobody before me, Ilya Zhezlov, knew what the true Christianity means and I have a direct hotline with Jesus (pretty much what Joseph Smith did).
Finally, who knows, maybe tommit will show that his allegations are not groundless, maybe he will present a cogent and highly convincing argument why he is right. If not, then his words are just air shaking. If he does, I think any reasonable person can decide whether it makes any sense or not.
I mean, sure, studying EBTs is important, but if we as a community can help debunking myths and wacky theories around EBTs, it would be even better.
