Sheep are herd animals that let themselves be driven by their shepherd. This image is sometimes applied to a human mass that lets itself be driven by an authority. Someone belonging to such a human mass is then pejoratively called 'sheep'. Often that term is used by people that differ from the regarded mass by not letting themselves being driven by the authority of the so called 'sheep'. They see themselves then usually metaphorically as solitary untameable tigers. Not seldom they form together with other presumed 'tigers' however a minority mass that lets itself also be driven by an authority, be it another one than that of the majority mass. Because this minority mass differs from the majority mass, with that elicits disapproval from the latter mentioned, but lets itself also be driven by an authority, along the aforementioned metaphorical line the proverbial term 'black sheep' is more applicable for someone from that minority mass. For the term 'black sheep' is often used for someone who due to his deviation from the norm elicits a disapproval. Many considered 'tigers' are thus actually 'black sheep', but with that also 'sheep'. Some moments of self-reflection are for them thus befitting before they are going to use pejorative terms for others.
