Vegans are going to have to re-evaluate their life choices. It might be much more cruel to harvest a field of soybeans than it is to kill a cow.
2) I find your debate that "structure/texture changing plant matter making sounds is the same as animal matter/brain feeling"... interesting.
How? Unlike cows, soybeans are harvested at the end or near to the end of it's lifecycle.
Also huge amount of cows now require vast amounts of soybeans. So if you want to decrease harvesting of soybeans you need to first decrease farming of cows. So vegans are already in favor of decreasing soybean production.
