Controversial post coming up.
WWII. Cattle trucks trundling across Europe towards slaughterhouses. Trucks packed with suffering animals bleating or roaring with pain and misery, wondering what was happening to them. Trying to protect and nourish and reassure their offspring, right up to the moment when they were exposed to poisonous gas.
Remind you of anything? Well, of course it's not the same is it? Nowadays, the animals have their throats cut, or are rendered unconscious by carbon dioxide.
I'm not preaching. I'm just asking you to think about it.
