The betrayal of trust carries a heavy taboo.
— Aldrich Ames

It is our attitude toward free thought and free expression that will determine our fate. There must be no limit on the range of temperate discussion, no limits on thought. No subject must be taboo. No censor must preside at our assemblies.
William O. Douglas taboos quote

At least one way of measuring the freedom of any society is the amount of comedy that is permitted, and clearly a healthy society permits more satirical comment than a repressive, so that if comedy is to function in some way as a safety release then it must obviously deal with these taboo areas. This is part of the responsibility we accord our licensed jesters, that nothing be excused the searching light of comedy. If anything can survive the probe of humour it is clearly of value, and conversely all groups who claim immunity from laughter are claiming special privileges which should not be granted.
— Eric Idle

Tamed as it may be, sexuality remains one of the demonic forces in human consciousness -- pushing us at intervals close to taboo and dangerous desires, which range from the impulse to commit sudden arbitrary violence upon another person to the voluptuous yearning for the extinction of one's consciousness, for death itself. Even on the level of simple physical sensation and mood, making love surely resembles having an epileptic fit at least as much as, if not more than, it does eating a meal or conversing with someone.
— Susan Sontag

Everyone has taste, yet it is more of a taboo subject than sex or money. The reason for this is simple: claims about your attitudes to or achievements in the carnal and financial arenas can be disputed only by your lover and your financial advisers, whereas by making statements about your taste you expose body and soul to terrible scrutiny. Taste is a merciless betrayer of social and cultural attitudes. Thus, while anybody will tell you as much (and perhaps more than) you want to know about their triumphs in bed and at the bank, it is taste that gets people's nerves tingling.
