Mutt and Brian's vitriol is a response to having exposed them for the frauds they are. So it's all name calling now. The fact that John puts up with this is telling of the core sensibilities and purpose of this forum.
Neither of us are frauds. Tell you what, I'll happily post my credentials, certificates etc here for all to see. Assuming you wish to retain your anonymity, how about you post your credentials to a Moderator of your choice, and we'll see who the fraud is.
As for staying on topic, readers have a right to expect people are what they say they are. Not all are aviators, and if they are, may be reading, or asking questions to further their knowledge. Either way, getting answers/information from an individual who clearly has no aviation experience, though pretends to have, leaves them misinformed, which can have grievous consequences.
