Calling it an art does not make it less cruel. That something is lucrative does not mean it's nice (ask slavery victims). Please consider not buying animal products, you can easily do without it. Thank you.
Ah yes, the old "Eating/Kepping animals is just like slavery, you're all monsters" chestnut... Do you really think that anyone is going to see this comment and reconsider eating meat, or wearing leather? Because "that nice _cies_ person on the internet told me I'm a terrible human being"?
If that makes you re-evaluate your choices in life, that could be great for the chicks. I never called you a terrible human.
