I don't feel uncomfortable with what he says. I considered what he said the first time he said it, thought hard about it and disagreed with him.
I have never, ever seen a fish die purely from being captured, do not believe two toneing in fish is caused by stress, do not believe a properly kept keepnet harms fish, have had enough repeat barbel captures on hair rigged baits to refute his claim, etc, etc.
What I feel uncomfortable with is John putting our sport at risk with his irresponsible comments. He should now consider the feedback and shut up.
