Have you read a single post in this thread? Humans can live without meat, and you can get the necessary proteins and such in other foods.
Note:
Another day without eating meat at all, fish tastes quite good. I feel a bit better today.

Fish meat is meat. I never understood why people think eating fish means they're giving up meat. If you eat fish, you're not a vegetarian.
Humans can live without vegetables, and you can get the necessary fiber, vitamins, and minerals from other sources.
Note: Had three steaks last night, a glorious eggs benedict with canadian bacon for brunch, and out for more steak tonight. I feel fantastic!
Fish is not considered meat, this is why:
As a generic culinary and butchery term of art, "meat" refers to the muscular flesh of a mammal. This is the definition most commonly applied by governments in meat product regulation and food labeling, and in religious rites and rituals.
Because of this I don't consider it meat, also eating fish is very healthy. Even in my culture in which I live, people don't consider fish as meat. I never said that I'm a vegetarian either.
So is poultry meat? Last time I checked, birds are not mammals? You do realize that at the cellular level, a muscle cell from all animals are relatively indistinguishable. They all use a homologous set of genes to achieve the same function. Ultimately, for you to have your fish, an animal must give it's life.
