Sheep are used throughout the Bible to symbolically refer to God's people. Sheep are mentioned over 500 times in the Bible. I consider myself an Agnostic.

Christians traditionally refer to Jesus as the "Lamb of God." 

"It is he who made us, and we are his; we are his people, and the sheep of his pasture." Psalms 100:3

“Behold, I am sending you out as sheep in the midst of wolves, so be wise as serpents and innocent as doves" Mathew 10:16

I detest the way sheep are used in modern day pejorative terms, just like "liberal", hence the reason I threw your original use back at you. No offense to you or sheep! 

Do you remember the Trump tweet from a few months back, quoting Mussolini? “It is better to live one day as a lion than 100 years as a sheep.” 

Substitute Wolf for Lion and it reads the same. Something to think about as you go to the polls to cast your vote for Trump.
