What you don't understand is that this board is a community. Everyone here is entitled to an opinion, and sometimes we agree and sometimes we disagree. I like some practitioners that other guys hate, and I hate some that other guys like. That's fine. Sometimes we exchange private messages with like-minded posters and choose to share additional details, and sometimes we get irritated and decide to block each other. Sometimes we even find ourselves blessed with the presence and insights of a few practitioners themselves. Sometimes they are gracious and sometimes they get defensive. That's fine too. We're all human.
None of us takes anything we read here as gospel, and none of us has to be "warned" about anything. We certainly don't need lectures from newbies about taking things with grains of salt. We're a pretty salty bunch without you.
Your choice of subject line is melodramatic and, frankly, insulting and offensive. I suggest you lurk a little--and learn.
