Before some rep-fishing (no pun intended) person comes in and states "People can eat what they want", I'm not saying they can't.
This question obviously applies to those who don't eat meat for ethical reasons, and not due to taste or health reasons.
It's a genuine question: If one is against eating animals, why eat fish?
Some do it as a transitional period to get used to a lower meat intake. Some are forced to by parents (as a compromise). But that can't be everyone, so what other reasons?
I've never met a pescetarian (obviously have met a vegetarian), so I'd be interested to know.
Obviously there's no 'right' or 'wrong' answer here, as everyone can eat as they choose.
