,sorry,but at one time it was probably a cute and fluffy little thing skipping around a field.
A fish isn't cute or fluffy. It's a basic food and one of the healthiest for us humans. It's better for people to consume, when compared to pork or beef.
It has those omega threes, EFAs which are essential for good health.
Fish is better when it's fresh, just been caught and cooked. Why try to ruin a good thing with something that's been processed?
If you want to go on a crusade, why not stop the slaughter of more complex beings, like pigs, cattle or chickens?
Pigs and cattle, especially, are mammals like us. A cow's head is bigger than a human's. Does this mean the brain is bigger?
