Never have never will, won't run trips for killing hates, just my style. Ive had clients ask after booking about killing them and work my way around it or try and educate them on why I don't believe in it.
That said, what is black and white to us isn't so much for everyone else, and maybe just like boycotting the places that buy or sell native steelhead, book with guides like Bob, ect that don't believe in it and probably take the job as more then just that and teach more then just catching.
you're never going to get everyone to see things the same way, they have their rights by law, but you can do your part. my $.02

Phill-I use pissing in a pool your about to jump into as my analogy
