My friend it's just a saying that is very old. Hunter's hunt birds and this is where they derived the saying. Remember the Bible: JUDGE NOT LEST YE BE JUDGED!
Words matter, and as our understanding of social justice evolves, our language evolves with it. Just as it would be unacceptable to use racist, homophobic, or ableist language, phrases that trivialize cruelty to animals will vanish as more people begin to appreciate animals for who they are.
