A mass of idiots who pride themselves on being silent and making up a
significant portion of the population (never actually more than 50%, or anywhere close). In reality, they are brain-dead cretins afraid of opening their mouths because they know any informed individual can prove them wrong; rather than being open-minded and engaging in debate, they hide from any debating what-so-ever as a way of preserving their stupidity and ignorance. Thus they are "silent" because you won't hear them participating in
intellectual discourse but, come election day (or any other major vote),
you will see these jackasses show up to cast votes.
