One thing I've noticed among the high ranked members is, Each time a newbie (not referring to those only that has newbie tag to their profile) creates a post that is contradicting to the beliefs, most high ranked members always critise instead correcting or teaching.
maybe you should have included a topic you had in mind although that might change the discussion altogether.
I agree with what you said here but also let's not ignore the fact that there are a lot of topics by the newbies that do deserve the harsh criticism by other members. for example those who are too lazy to do a search before posting about something that was discussed to death here a million times. or the topics that the newbie reads some FUD and then starts something here spreading the same thing. for example I personally hate those topics that start with "we all know that [blank]...." and [blank] is usually a false statement or an FUD they are trying to say is valid before they continue with making a conclusion based on that.
not to mention that most of these topics by newbies are obvious shitposts. most of them don't even come back to their own topics to read a single one of the replies! they just post something and run away, possible only to increase their post count or have their topic stay on top (while advertising their own signature like ref links) by creating something controversial.
