well, as much as i love cheeseburgers and participating in the rah-rah, MOAR BACON!!!! culture, going vegan can be a very good choice for some people.
my mom is dairy-allergic, so she already had to stay away from dairy products like cheese and milk, yet when i was a kid she was often sick, eventually she went completely off of animal products in an effort to keep from getting sick. Lo and behold it worked, she finally could live like a healthy person, and no she did not become protein deficient and lose all of her strength, it had no adverse effects on her health. Humans really need a lot less protein than we normally eat, remember that until the last century or so, people rarely ate meat like we do now, and still today, most of the world eats very little meat compared to the western world. There are plenty of ways to get the necessary protein humans need
its probably a lot better healthwise to stay away from meat, but i think the ability to eat meat was a big advantage before we discovered farming, being omnivorous gave us a lot of flexibility in finding food, as you couldn't always rely on finding enough plants to eat, we could eat meat if we had to.
But all that said, i still love hot dogs, and burgers, and brats, and bacon, chicken, and just about every meat in the world (will be trying gator sausage on a stick at the taste of chicago next week!)
