I have been dealing with scuba extremists lately, and it is beginning to bug me. I won't call them out here. I just wonder if it is possible for an extremist to look objectively at his or her own beliefs. I wonder if others can recognize when an extremist has gone too far.
One of my favourite quotes is from the British philosopher Bertrand Russell:
"The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts."
