Yes i eat fish and dont realy have anything against it; oh ok maybe i feel a little guilty when im cooking fish in the kitchen at my place, the kitchen being where my main tank sits and my fish look on towards the pots and pans.
But either way, people are designed to have fish as a part of their diet as we have relied on it so much throughout our evolution so i don't see whats wrong with eating a fish as long as its not domesticated or nothing.
