zebo - // I used to work with what I can only describe as a militant vegetarian, ramming it down everyone else's throat at any opportunity, but she ate fish! Apparently fish didn't count to this hypocrite, you're either vegetarian or you're not, you're simply limiting meat intake. //
The argument for pescatarians is that meat and poultry are bred and slaughtered in cruel conditions, which makes it morally wrong to contribute to that situation by eating meat - but fish are not farmed and caught without undue cruelty, so eating fish is seen as morally acceptable.
