I am not sure that it would Brian.
Inasmuch as it encourages people to show a measure of tolerance about opinions different than their own, then yes.
But inasmuch as it is a counsel of relativism - all opinions have equal merit because nothing can be definitively proven -then no.
All opinions are not equal, in my view. That way madness lies! Sure there are grey areas, but no one is surely arguing that my views on golf architecture and music are deserving of the same weight as those of Jack Nicklaus and Mick Jagger respectively?
