If a person isn't vegan, it's not what they eat, but who. Some people don't give a fuck about other people being racist, not caring about shit is the norm.
Those were two very interesting sentences you put together.
There are some studies that show mycelium may show signs of sentient behavior. Also, trees and plants are shown to communicate and warn other plants of dangers. Heck, even trees are known to leverage mycelium networks to communicate.
I guess the question is: Who the heck have you been eating?
I think vegans are crazy if they care about the 99.9% to 100% animal product free part more than about the, say, 50% to 99.9% part. The rest of them aren't.
Agree on that. I think the biggest issue is that the most extreme (caring about the 0,01%) tend to be the most vocal and agressive while they are the absolute minority of the group. All the vegans i know irl will not talk about veganism until asked about something (myself included).
It's only the annoying ones that want to talk about it at length, so those are the ones you remember. There should be a name for that sort of phenomenon.
