One must discriminate to make value judgments. Otherwise, one is doomed to be defined by others and their value judgments. Values are what form our decision making and what makes for discriminations.
Universalism is an Utopian ideal, but is not practical in the real world of politics. One must make choices about where to draw lines, and where and what makes for the "best life", for oneself and others.
Our Constitution allows liberty of judgemnts, where religions seeks to subvert such liberty. Our society, while free and liberal, is also in need of solutions to societal ills. Such ills as budget deficits, to local delinquency are of concern to citizens. The answers are complex and won't be easy to come by, as they infliterate into our very cultural meleiu. What makes America American.
Liberty is such a value. More than once, I've heard that liberty is associated with license. "License" has to be defined. The normal definition of "license" is offical permission to carry out a particular job by the proper authorities. Licenses are legal contracts. But, the context might make a significant differnce. The religious would define license as "against God's law". Such definition is a narrowly focused, but widely defined, as religions would define "God" and "law" differently. This difference is what makes for religous wars. And such wars are justified in the name of "God".
Our Constitution limits only those who'd limit others in their liberty to 'find their own way". Choice is a value in America, because we believe in individual liberty of conscience. But, American families are broken and Americans have lost thie "sense" about value, when they don't seem to care about anything other than watching the next episode of "The Bacholor". Children are raised with little sense of self, because their parents are too busy to make room for baby. I don't value this attitude, because young people need guidance, so that they can make wise choices about thier lives. Parents and others in the community are needed to encourage such emotional and character development.
Discrimination means that making choices might mean separating onself from things that are not valued, as much. Prioritizing such values is a necessary "education" about oneself and goal setting.
In our culture, "discrimination' has gotten a "bad" or negative definition, because it has so often been associated with racial, or sexual inquality. Equality is an American ideal, so the politically correct definition of discrimination never gets investigated. It is swallowed without thinking about what it might mean.
I am glad that America allows for inviduals to discriminate about thier own values and purposes, otherwise, I would be discriminated against!!
