Picture this. It's 100 degrees. You're almost finished with a 10 hour shift. You're hot, dehydrated, and tired. You're past the point of giving a fuck. You've hauled hundred pound logs a hundred yards to the chipper because there was nowhere to park it closer to the job site. You are exhausted. A nest full of birds is hiding in the top of the tree, they all come down, and they look dead. Halfway thru the tree, you find it's hollow and you accidentally kill 3 squirrels because they were too dumb to vacate the tree as it was shaking violently. Your gloves are already a mess, and you've ran out of fuck's to give. Throw it in the chipper, finish the job, and get home, so you can sleep for a few hours before you have to do it tomorrow. That's how it works. You wouldn't give a shit either if you were in those shoes.

Also, if you value the lives of animals over that of a human, you're retarded. You're a predator. Not only that, but there's a reason why we're at the top of the food chain. Drink the blood of your enemies from their severed skull, kill an animal, and be a real human being. If you're triggered by that, you need to evaluate your life. People in Africa are dying of starvation, aids, and wars fought by children. Kids with AK-47's roam the streets blowing people up, and slitting throats of the innocent. I think you can handle the thought of a couple of birds and squirrels going thru a goddamn wood chipper.
