The OP and the poll were intended to gauge how divers perceive the risk of attack from sharks. As explained before, the range of options provided were more than adequate to cover level headed responses. I believe the topic is appropriate for the Basic forum. If people don't like the thread the obvious solution is to avoid posting on it. If they don't think that the poll is accurate, there is nothing to stop them starting their own.
Your latest additions are:
'I don't care', suggests you'd be willing to jump into shark infested water regardless of the consequences. I don't accept that as a valid or rational response. If nothing else, excluding it from the poll is in keeping with the forums policy not to promote or sanction unsafe diving practices.
The statement that 'shark culling or finning is morally wrong' has nothing to do with the topic of the poll and OP. It is an inappropriate discussion for the Basic forum and extending the discussion to include those topics will only serve to inflame an already difficult discussion.
Evidently the thread and the poll are considered appropriate for this forum. In the region where we live this kind of assessment is very real and is being done consciously or unconsciously by many divers. I know of people who have been avid divers for much of their life and in the wake of our latest fatal attacks in our area now refuse to dive. Everyone has to decide at which point they will draw the line. Raising it as a poll on the forum seemed a reasonable and useful thing to do. It gives divers a chance to compare their assessment with others and discuss the factors that influenced how they arrived at that assessment.
Clearly I was being overly optimistic. If nothing else the thread to date serves to highlight how difficult it is to have a sensible, level headed conversation on the topic.
