That is exactly what i was refering to. The resultant change in evolution brought on by a very small group (1%) and succceding because they appear to be a much larger community than they really are. This is a poor example but say 1% of the overall population does solo. 5% of population have ;osting abilities on SB. all solo divers are among the 5% on SB. So 20% of Sb believe the barriers should be removed in regards to solo diving. So now run the logic backwards. 20% of SB are pro solo. there fore 20% of all dives are pro solo. 20% perceived or not can be quite a force. Now the removed stigma on the 1% overall becomes a life of its own because its looked at as 20% of the overall population. Now be have perhaps 20 percent that no longer think of solo as dangerous at all. Kinda of like the evolution of NITROX. Imagine what would happen if the barriers were dropped for wreck or cave diving. "We dont need no stinking line, That sign is for newbys and I have 30 dives in my book" I guess its the You dont know what you dont know.
Among other things, I think you may have misunderstood my question (assuming that's the question you are referring too) I did not ask how to change dive ops attitudes but rather are they changing. As perhaps a natural evolution of diving, similar to the gradual acceptance among the general diving population.
