Thank you for writing.
Just as you are appalled at factory farming practices, so are we appalled at the way people turn a blind eye to the teaching of Jesus, such as the sermon on the mount when it comes to compassionate living, and proceed to kill another living being.
A person cannot knowingly kill another living without hardening their heart toward the animal they desire to kill. The same applies to the fruit of the Spirit that Paul teaches us about in Galatians 5:22-23.
If you are really going to follow the early sages, then follow the New Testament ones, too, and God's first commandment to eat only plant foods. We do not need to eat any animal products to be healthy. In fact, we'd be a lot more healthier if we followed God's original diet for us.
In the Love of the Lord,
Frank and Mary
