i'm stuck with a vegan housemate, also, and the thing that i've always observed with this is they are full of aversions. myself, i had to fight a lot of aversions to switch to a diet that wasn't leading to chronic asthma and rashes all over my arms and feet and hips. once people have got fear conditioning wired up, it's very hard and scary to get rid of. the only thing that finally ends a regime of this kind of shit is where a lot of these fear burdened people actually die and those who have always opposed it or chose to fight it help bring on better times.
but it's probably going to get a lot worse yet. brainwashed drones are a lumpen group that mostly won't wake up until you hit them with so much pain they realise the pain in their minds is an obstacle.
