OK, yet another thread that has morphed into something else. Let me be clear - just because someone else does something wrong, it does not diminish the good I do when I do something right. I can not make people:

release wild fish
fish legally
not floss
not snag
etc., etc., etc

By example, I MAY make someone think about their actions. But if I just give up and say that because someone else does something wrong that I will not do the right thing makes me an even bigger part of the problem. BECAUSE, I KNOW BETTER and because of that have the responsibility to act ethically.
