Consumption of beans is always ethical

Are you selling or buying the experience of kicking a puppy?

Shoot the puppy while you're at it

Some would say it doesn't matter if you shoot the puppy either, so long as you admit to being too incompetent to train it

You don't really "consume" puppy kicking or orphanage burning.

Your point would be more effective if you said something like "eat a puppy" and "buy child porn", but I guess you didn't want to sound like Vaush.
