Well, if you want to do it right, you don't just "not discuss" the orthodoxy, you go out of your way to make discussing the orthodoxy very clearly forbidden on the research circle. You put "we won't allow anybody to talk about lightning" on the first paragraph of your institution's code of conduct. You actively censor people discussing it, and do all you can to erase it from their history.<p>On a related matter, people actively insisting that you discuss the lightning issue may be consciously trying to do the exact opposite, and get you in trouble. And, of course, if discussing the orthodoxy gets people in trouble, that's a different issue from the orthodoxy itself and you may be more or free to talk about it, or maybe less, it has to be independently evaluated.
