Exactly what I have been trying to say for years.
I stopped eating meat at age 6. Why? Because (brace yourselves) I don't like it. It tastes vile to me. When I got to be a grown up, I tasted it a few times - nope, still vile. Plus I'm cheap - meat is expensive, and I like eating lower on the food chain as a general principle.
Now, I truly do not care what others eat (provided I don't have to pick up the tab for your filet mignon). But I have also had the experience of people looking at me like I have 20 heads when I say I am a vegetarian.
We don't subsist on plain lettuce leaves. Ever eaten a bean burrito? Fettucine Alfredo? Cheese pizza? Then you ate vegetarian food. And lived.
