When parousing facebook groups surrounding ambulance services (voluntary and paid) I was reading
SJA Facebook Group.

Why must during any discussion a post be preceeded by how big a cock the person has (or is?). For example

"As a duty manager, ETA, Blue Light driver and Ambulance trainer (not to mention 18 years experience of doing motorsports cover)..."

 Would these people speak in this way in person? Is it the same as those people who insist on emails ending their name in a list of post nominals like a list of sexual conquests?

Can people not express an opinion in a manner convincing unless they state all the things they have done? Does a pecking order exist like an exciting game of Top Trumps?

It gets even better when there is a disagreement and the titles list get longer and longer. People begin arguing about who has the most "experience" and start to bring other parts of their life (using the term loosely here) such as

"Im a qualified chemist and work as a materials scientist :P"

Seriously who gives a fuck? How is this organisation supposed to be respected when the members think the correct way to gain respect is to have a pissing contest on a public forum?
