Imagine… as a young student 
you look forward to driving or legally drinking. NOW imagine that all brown eyed people get to have this “milestone” BUT blue eyed people do not.
Brown eyes get to vote. Blue do not. Brown eyes can legally marry. Blue cannot. Etc.
Everyone is entitled to all the rights and freedoms set forth in this Declaration, without distinction of any kind, such as race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status.
