i see what you mean, man...
but look, as you may want to hear, perspectives vary from country to country.
in brazil, for instance, cattle and soy are among the biggest "commodities" in the country.
in our parliament there is a really strong and big group of politicians that push the interests of the wealthy farmers - many people suspect they are linked to the new policy of the brazilian government regarding the amazon to make room for new crops. and bolsonaro is pretty tied with this group, here we say that the three B's have elected him "bible, bullet and beef" (bala, bíblia e boi).
so... is there an agenda to promote veganism? maybe there is. it is profitable for many people. but the same thing could be said about cattle.
the truth behind this kind of polemic issue is rarely simple. if it seems simple and obvious it is a good idea to double check facts.
