Not read the whole thread, but will reply to the OP with my experience.
DP and I have recently "gone veggie" because we do not like the way that animals are treated and eventually killed in the meat industry. We can't afford to eat organic, free range meat so made the decision to cut meat out of our diet. We did start having chicken, free range but not organic, but since "going veggie" i have not enjoyed eating it so have cut it out completely.
We eat fish because we have less guilt i suppose about eating something that has lived a good quality of life, free, before it was killed. We have discussed eating game and yes, i don't think i would have a problem eating wild pigeon and rabbit, however its not readily available so wont go out of my way to eat it. Also, have always been wary of game being un rotten, iyswim, and again, its expensive - i suppose i could go and shoot it myself and i would feel less guilty about doing this than eating factory farmed meat.
So are we strictly vegetarian? I guess not, we just don't eat meat - but whats in a name? Does it matter? I think we do have to recognise that we are omnivorous and fish is a good way of getting vital nutrients. I also think if the meat industry wasn't the big pile of chemically pumped mistreated animals then i would be happier about eating it. I am certainly not overly sentimental about animals, i just think that all living creatures are entitled to a decent quality of life and i don't feel that farmed animals receive this, or that i can't garauntee this enough to myself to feel comfortable eating something that may have suffered just so it can be on my plate.
