High quality conversations are broad, multifaceted, and regularly cross many many domains... to automatically ban an subsection of conversation becase of the existence of a single-word is inexcusibly stupid... my and my accociates all started our investment careers by trading these artificially slow, overegulated, trash tokens called public stock for years before learning how to make serious dosh in no time... none of us would ever trade stock and more... make no mistake attempting to silence conversation anywhere about anything is vile censorship and is always a last ditch effort, and a clear sign of fear from opressive 'authorities'. if you really 'think' otherwise then it's going to take too much time to fix you and i'dfe say have a nice day in the sheep padock.
