Democracy is a pathetic belief in the collective wisdom of individual ignorance. H. L. Mencken
Arrogance, ignorance, and incompetence. Not a pretty cocktail of personality traits in the best of situations. No sirree. Not a pretty cocktail in an office-mate and not a pretty cocktail in a head of state. In fact, in a leader, it's a lethal cocktail. Graydon Carter
I do sometimes accuse people of ignorance, but that is not intended to be an insult. I'm ignorant of lots of things. Ignorance is something that can be remedied by education. Richard Dawkins
If you belonged to a political party or a social club that was tied to as much bigotry, misogyny, homophobia, violence, and sheer ignorance as religion is, you'd resign in protest. Bill Maher
Where justice is denied, where poverty is enforced, where ignorance prevails, and where any one class is made to feel that society is an organized conspiracy to oppress, rob and degrade them, neither persons nor property will be safe. Frederick Douglass
