I say that because most of the articles on meat alternatives are written from the perspective of "if only Americans can stop eating hamburgers!"
First off, in terms of global solutions, that isn't going to fly. Try going to Italy and telling people "we've replaced all your meat, with a ground beef alternative!" and see how pissed people get. Countries around the world have culinary traditions older than America itself. Many of these traditional preparations of various cuts of meat are a huge part of culture and history.
Second off, I, an American, don't even eat hamburgers[1] more than once or twice a year. And I'm not going to switch all my meat eating over to meat alternative hamburgers.
Of course replacing some meat is good, my main complaint is how so many articles reduce American food to just a few categories.
I have the same problem when friends come to visit from overseas, or even friends who've been in America for awhile (sometimes years!) who have no idea that American food is anything other than burgers and pizza.
[1] I eat sausages a bit more frequently, which I could fill with a plant based alternative.
