That's part of the funzies of the forum, and also part of the reason that humble and thick-skinned newer members will likely grow in rank faster.. as long as they are learning along the way, attempting to grapple with topics, and trying to post interesting points from their own experiences.
You are right, I have seen a few thick-skinned newbies who ranked so fast in less time just due to their general or technical skills. I have seen members registered on BTT after me, and they have become legendary due to there technical knowledge and the services they provide. That's why learning on the way is necessary if you want to grow.
For sure sometimes the teacher is wrong.. and even the teacher might sometimes be guising himself/herself as a teacher when s/he is just faking it and hiding behind the quasi-anonymity of this kind of a forum.
It is good not to argue for the mere sake of it, but sometimes you can argue, and/or present facts, logic and even variations on the conclusions that might cause for some discussion points, to the extent the newly provided facts, logic and conclusions are not totally stupid.
Yeah, teachers can't be right every time and we should not hesitate to ask questions and that's exactly what I meant to say, that we should not feel embarrassed when roasted by teachers because if we want to learn something then we should not care about what will come from their mouths for you all we as students should care about useful answers to our questions that are confusing.
You can sometimes also get away with some kinds of discussions that you could never have in real life because sometimes you might not want to present certain ideas to people in the real world or you might not even have any audience for your ideas within 2 hours commute..
It means BTT allows us to showcase our ideas that might be of no worth to the outside world, and that's true. The reason behind it might be, that those who have found BTT are somehow familiar with BTC and what is blockchain because some are referred by any other BTTian or some have found it on news sites etc. The source would be any, the point is they have some idea about it but most of the outside world people, have no or lesser idea about it and once you start lecturing them their nature makes them to convert the discussion into an argumentative one.
Maybe that's why I like BTT, people value other's opinions and point out mistakes too. Be legit
