I find your reference to "concentration camps" in relation to livestock finishing feedlots and slaughterhouses to be tremendously inappropriate. Please find another way to shock and horrify readers into treating food animals more humanely.
It might not have been your intent, but you are reducing the victims of actual concentration camps to the status of food animals.
If you do indeed believe that battery farming of livestock for meat production is worse than human genocide, we cannot have a rational conversation about ethics or animal rights, as we do not agree on the necessary foundation premises.
We must differentiate between concentration camps and death camps. Concentration camps are just large prisons, death camps are for genocide. Also, food farms are for animal genocide.
