The fact that we even have rights is a privelege...

"Rights" are a construct of man...consider yourself priveleged to be alive, to be able to experience the joys of our planet, to be able to hook a creature as magnificent as a steelhead...Once you say it your right you have abnegated the rights of the fish...

Do our 'rights' extend to fishing a species into extinction.

People have also been committing murder since they evolved, using the same argument you apply to fishing this would also make murder a 'right'. Sorry, man says we cannot murder fellow men, man says we can either fish or not fish. How can this be viewed seriously in any way other than privilege?
