Just like beauty, it is the eye of the beholder. Many people define obscenity as something somehow sexual or suggestive of sexuality. Some of these people find obscenity every where they look--it just shows you where their minds are--and makes you shake your head and say, "Well, if YOUR mind wasn't in the gutter to start with, that would not even have occurred to you!"
MY definition of obscenity will not be found in the law books, nor will any judge pass a legal opinion. However, this is how I define the word:
The outrageous size of the salaries of politicians, corporate CEO's, professional athletes and the skyrocketing price of gasoline. The shipping of our jobs offshore, the lying, cheating and stealing done in the name of balancing the government budget, as they increase their own perks, and slash the money to education, health care and social security for seniors.
The cost of living rises each year, but seniors get no raise in their checks. After 3 years, a raise is finally given, not anywhere near in proportion to the prior 3 years of inflation, then, with the other hand, that raise is taken right back by increasing co-pays, taxes and other things charged to these seniors against their checks. THAT's what's obscene to me!
