>1. There are no special chemicals or compounds (protein, iron, etc) in meat that can not be found elsewhere.
I never said there were. The problem is that they are not easily found elsewhere, in an appealing form, in sufficient density, like they are in meats. If you really love lentils or some crap like that, more power to you. The rest of us think a lot of that stuff is nasty.
>2. The protein myth is strong in the US, but it is hard to find almost any food that lacks it. Have you ever known someone who was protein deficient, anywhere? It is estimated that 6% of the US is veg and 40% of India is vegetarian. And these people are typically healthier then the rest, not deficient.
Wrong. Look at the average height of people from India. Now look at the height of children of Indian parents who immigrate to the US. Compare it to their own families back in India, to eliminate the effects of socioeconomic differences between groups/castes there. There's a huge height difference, and it's because of the readily-available protein in the diet. The kids end up growing much taller than the parents even, and much taller than their cousins back home. I've seen it myself up close. It's not genetics, it's diet: childhood nutrition has a huge effect on height.
So no, it's not a "myth", and yes, lots of people are protein-deficient, it's just not as readily-apparent as people who are visibly malnourished as in truly impoverished places where they're literally starving to death.
And as for American vegetarians, they fall into at least one of two groups (there's a big overlap): 1) people who are already adults, and probably aren't extremely physically active/athletic, so they don't have the high protein needs that growing children do and can take advantage of, and 2) people who are basically religious about their vegetarianism, so they're extremely well educated about what foods contain what, and go to a LOT of trouble to make a balanced diet out of it (whereas the rest of us just throw a little meat into our diet and avoid excess and otherwise don't have to spend a lot of effort or attention on our diets).
>3. Speaking of India. You think vegetarian food cant be made to taste good, or is too bland? They have had it mastered for thousands of years.
Yeah, if you like Indian food. People who didn't grow up with it frequently don't. At least it's not nearly as bad as some southeast Asian foods, like Indonesian, but it's pretty much inedible to western people unless they tone down the spices.
>Just because you had one bad veggie burger, does not mean there is not great veggie food out there that would appease most of the world.
No one's made a good veggie burger, and that's because it's impossible. If they could do it, they would do it, because there'd be a lot of money in such an invention. They all taste like cardboard. The only way you're going to make something taste like real beef is to either use real beef, or chemically or biologically replicate the beef somehow. You're not going to achieve that by growing some readily-available plants and mixing them up somehow; that's like thinking you're going to build a Ferrari out of typical bicycle parts.
>4. And speaking of taste, taste is not a static condition. Yes, there are some things we have evolved to like, but your taste buds themselves are malleable - not fixed as most people will tell you if you go on a diet for a couple weeks.
Basically you're advocating somehow either forcing or convincing entire societies of people to suddenly change their taste preferences. That's not likely to happen. And don't forget, here in many western nations (esp. the US and UK probably), we are exposed to the cuisines of other nations a lot (though sometimes they're heavily modified to sell to Americans--Chinese food is infamous for this). It's not like Americans have never tasted Indian food; we have. There's lots of Indian restaurants here, plus various other exotic cuisines (middles eastern, Ethiopian, etc.). It hasn't caused Americans to all suddenly switch.
