Exactly! And....my own personal research has shown an astounding number of vegetarians/vegans with major health problems. Weird stuff too. Just my personal opinion.
That's typically because they eat a crappy unvaried diet, not because they're not eating protein from meat. It's quite easy to eat a healthy vegetarian or vegan diet if you're willing to learn a bit about what you're eating and to actually cook your own food.
Lots of people in the US eat a crappy unvaried diet anyhow, regardless of if they're eating meat or not.
